Basic Integration… How? (NancyPi)

Published on August 22, 2018 by

MIT grad shows how to find antiderivatives, or indefinite integrals, using basic integration rules. To skip ahead: 1) For how to integrate a polynomial with the POWER RULE, skip to 1:35. 2) For how to integrate NEGATIVE POWERS of x, FRACTIONAL POWERS of x, and RADICALS/ROOTS, skip to 6:12. 3) For how to integrate x^(-1), or 1/x, with the LOG RULE, skip to 7:23. 4) For examples where you use more algebra to rewrite before integrating, to SEPARATE the numerator of a FRACTION, or EXPAND a PRODUCT in order to use the Power Rule, skip to 10:00. 5) For basic TRIG and EXPONENTIAL examples that use rules from the Table of Integrals, as well as trig identities, skip to 11:36. Nancy formerly of MathBFF explains the steps.

Follow Nancy on Instagram:

1) POWER RULE: If you're integrating a polynomial, or just a power of x, you can use the Power Rule on each x-term in the polynomial. The Power Rule says that for a term that's just a power of x, such as x^3, you can integrate by raising the power by 1 AND dividing by that number (the new number you got by increasing the power by 1). For example, the integral of x^3 would be (x^4)/4. If there was a constant multiplied in front of the x-power, you can keep the constant and integrate the rest of the term (Constant Multiple Rule). For example, the integral of 6x^2 would be 6 times (x^3)/3, which simplifies to 2x^3. You can repeat these steps to integrate every term in the polynomial and string them together for the full integral. You can also keep the addition and subtraction between the terms (because of the Sum and Difference Rules). NOTE: The anti-derivative of a constant (just a number) is always that number times x (the Constant Rule), so the integral of 1 is 1*x, or x. At the end, it's very important to remember to add a constant of integration, to include a "+ c" at the end of your answer, when it is an indefinite integral (integral with no limits). ANOTHER NOTE: The Power Rule only works when the power is not -1.

2) NEGATIVE & FRACTIONAL POWERS, and RADICALS: For negative powers, you can still use the Power Rule, as long as the power is not -1. For fractional powers, you can also use the Power Rule. When you increase a fractional power by 1, you will have to simplify the power (before integrating) by getting a common denominator. For roots, like the square root of x, it's best to rewrite the radical as a fractional power, and then use the Power Rule.

3) IF THE X POWER IS -1 in the integrand, either written as x^(-1) or 1/x, you have to use a special rule, the LOG RULE, that you can find on a Table of Integrals. It says that the anti-derivative of x^(-1), or (1/x) is the natural log of the absolute value of x, plus c.

4) MORE ALGEBRA: Sometimes you may need to do a bit more algebra before integrating, so that the integrand is in a form that fits a basic integration rule, like the Power Rule. If you're integrating a rational expression, you can sometimes separate the numerator, or break the fraction into separate fractions, simplify each term, and then integrate with the Power Rule. If you have a product of x expressions, you can multiply it out, or distribute the factors so that you have just a polynomial (and can use the Power Rule).

5) TRIG & EXPONENTIAL: You can find a lot of trigonometric (and exponential) integral rules in the Table of Integrals. If you don't see it in the table, you may need to use a trig identity first, to rewrite the integrand into a form that you can integrate.

    Please Nancy save my life maxima minima please please please…. With word problem also. It’s urgent.

    • Math and Logic 4 years ago

      I suspect you’re being asked to find the maxima/minima of a quadratic. For example if a rocket is launched in the air with height given by h(t) = -16t^2 + 128t + 10 (h in meters, t in seconds). You can want the vertex. The t coordinate (often you have x instead of t) is given by t = -b/(2a) = -128/(2*-16) = 4. The rocket reaches its maximum height after 4 seconds. To find out what that height is, plug t = 4 into the function. h(4) = -16(4)^2 + 128(4) + 10 = 266 meters.

    Thank you soooooooo muchh mam………

    Is there any way for finding the constant or it is impossible to find..?

    • NiHaoMike 4 years ago

      It depends on the use of the integral. When integrating data from a sensor, the constant is set by a “reset” when the system is in a known state. For example, a computer mouse works by using a laser to sense its velocity relative to the surface it’s on. The computer integrates the readings to move the pointer on the screen. Because of drift due to inaccuracies, the pointer often gets out of sync with the actual position of the mouse, at which point one fix is to “reset” the integral by moving the mouse into a corner.

    • Math and Logic 4 years ago

      If you’re given a pair of numbers to plug in to the integrated function, yes. That’s called an initial condition.

      No idea what that other guy is talking about.

    • Jayden Dickson 4 years ago

      The derivative of a constant is always zero. So yes, it is impossible to find the constant.

    • 984francis 4 years ago

      As NiHaoMike says, it depends on what you are doing. Integrating between limits, C will subtract from C and thus disappear. Another practical case is integrating the bending moment equation for a beam, integrating the first time (actually the third integral) will give the slope at any point on the beam and it is necessary to evaluate C, integrating again (fourth integral) for deflection at any point, a new C appears and it is possible to solve for that too. It’s been almost 40 years since I did this stuff and I can’t recall how to solve for C in each case. I think it may be setting X at a point where it is known that the slope is zero and similarly for the deflection. So any term containing X will go to zero but C will remain, not sure, memory failure.

      Calculus is found in alot of palaces. It is found in physics(when studyig about gravity, thermodynamics, quantum physics), it appears in business(when studying about prices and other models), it appears in geometry, computer science, biology everywhere

    • Harjit Singh 4 years ago

      Depending on what role you do will depend on whether you actually use calculus. For example, if you are a web designer you won’t even touch calculus but if you are working in AI/machine learning you will utilise alot of calculus/linear algebra/statistics

    At the fractional part.. is 3/5*x^(5/3)+C a typo? Shouldnt it be 5/3*x^(5/3)+C?

    • Bookspeak 4 years ago

      No, since dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of 5/3 = 3/5, so when you take 5/3 out of the fraction (x^5/3)/(5/3)+C it becomes (3/5)*x^(5/3)+C

    • Warc Arden 4 years ago

      That integral has no answer. Make sure if that is the question or if it is sqrt(cosx)/sinx

    • Justdoit 4 years ago

      @Warc Arden my Friend ,all are telling me that it has no answer ,but why ,please tell me the reason?????

    • Warc Arden 4 years ago

      Justdoit yes it has no answer, I would like to know where you came across this integral. You can tell that is has no solution since there is no function which differentiated which will give cos (sqrtx)/sinx

    • Justdoit 4 years ago

      @Warc Arden i made it myself:) ,well thanks for your answer ,i am totally satisfied with your answer,my friend. Thank you very much:)

    each units of i costs rm10 and each unit of ii costs rm4. each unit of product can be sold for rm40. how can the company maximize its profits?’

  • Matthew Berrios 4 years ago

    To me it’s important to give small reminders of algebra steps because it’s a good reminder for a lot of us who forgot how it’s done. I appreciate those reminders, very helpful! The people who end up needing your videos are usually ones with weak algebra skills.

    • Michael Brown 4 years ago

      Think about it when you’re taking the derivative of a constant it becomes zero, right? So the derivative of x^2+2 = 2x, but what is the antiderivative of 2x? Is it just x^2? What about that 2? When we take the derivative of a constant it just becomes zero so when taking the antiderivative, we need a place holder for all the constants that became zero when taking the derivative

    This is the first video I’ve seen of yours, and I had to subscribe pretty much as soon as it started. I love the way you explain things in a way that’s not too long and drawn out but that is also clear and helps to explain things. When I was in college, I was going for high school education (math), but to become a high school math teacher, you basically have to become an engineer it seems. I never really got the whole Integrals idea. I was so lost in Calc 3 that I switched to middle school education just so I could be done with taking math courses. I’ve always loved math and wanted to learn it though so I’ll definitely be watching your videos and hopefully finally understanding all that stuff I could never get before.

    Hello Nancy, if by chance you read the comments : I’m sure, like myself, many would appreciate if you could number your videos, or if at this point it’s too much trouble to rename existing videos, perhaps make a very short video / add it in description somewhere, to give the best sequence in which to watch your videos (many are self-explanatory, though some cases aren’t that clear). To be honest, your videos may be the best math teaching videos, and I’ve watched a good number of different channels’.

    Dear Nancy, there are a lot of “invisibility” in math, and assumptions, ……no wonder I couldn’t wrap my tiny brain around it!
    However, Differentiation & Integration and all the courses leading to it in my senior high school year, were my favorite. I also had a very good teacher! Mind you though I learned everything in Arabic lexicon. For the fun of it, although recalling is painfully slow and fragmented, I’m intrigued to hear you explain it in English😊

    Should briefly mention that the +C is only for indefinite integrals (Integral sign with no super/subscript). Don’t need to know more about definites yet, but important to mention so that rule sticks better.

  • John Pringle 3 years ago

    Hello Miss Nancy. Many years ago I washed out of both civil engineering and geology due to my inability to grasp calculus. I ended up as an electrician, but my math shortcomings have bothered me all my life. Thanks to your wonderful style of delivery in your instruction, I am finally, inch by inch… getting it. You instruct at a comfortable speed level, you don’t assume that everyone is a genius who you are talking to, you don’t make mistakes or stutter or trip on your words at all. So many of these math videos are a race to the finish, with mistakes in them, but yours ? Very, very nicely done. Yes, as a retired old guy, I do study math just for fun. Man, am I an exciting date or what! In my own defence, I do play piano, write short stories, do graphic art and build and fly radio controlled airplanes. With some embarrassment, I feel I should add that when I study your videos, I can’t help but feel that I am sort of on a date. You are such a pretty Lady that I found it actually distracting at first to understand your lectures. But now I just put you in a clown suit with a big red nose, floppy red hair and all the crazy clown makeup on. Thanks Nancy. You are the best. (I do still try not to make any male body noises when I have your videos running. After all, a Lady in a clown suit, is still a Lady)

    • maxmiau 3 years ago

      I have the same questions some books that claim the actual usage and applications for calculus fail to demonstrate how they work in a low level, I assume that’s why so many people fail/drop calculus entirely.

    You are not insulting me. My college wants me to take a course on mechanics even though design – my major- should come under arts. I didn’t bother with calculus much in 10th and I barely passed junior college. I am watching a youtube video because I am dumb. The professor’s notes are made under the presumption that the student studied some stuff in school.
