Integration by Parts… How? (NancyPi)

Published on September 12, 2018 by

MIT grad shows how to integrate by parts and the LIATE trick. To skip ahead: 1) For how to use integration by parts and a good RULE OF THUMB for CHOOSING U and DV, skip to time 2:46. 2) For the TRICK FOR CHOOSING U and DV (the LIATE memory trick) skip to 10:12. Nancy formerly of MathBFF explains the steps.

Follow Nancy on Instagram:

WHEN to use INTEGRATION BY PARTS: If you have an integral to evaluate, and you don't already know how to integrate it, as is, then see if you can simplify it somehow with algebra. If not, try doing a substitution, like U-Substitution. If U-Substitution does not help, then you may need to use the INTEGRATION BY PARTS formula.

RULE OF THUMB: The first step to use Integration by Parts is to pick your "u" and "dv". As a general rule of thumb, whichever factor in your integrand gets simpler when you take the derivative of it, make that your u. Then make the other factor your dv (and include the dx in this dv). Note: This works if the part you chose for dv does not get any bigger or more complicated when you integrate it. After you've picked u and dv, then find du by differentiating u, and find v by integrating dv. Finally, plug everything into the integration by parts formula and simplify.

TRICK: You can instead use an acronym memory trick to choose the right "u". The acronym LIATE stands for Logs, Inverse trig functions, Algebraic functions, Trig functions, and Exponentials (in that order). If you follow those letters, LIATE, in sequence, whichever type of function you find first that you have, make that your u. Then, make the next thing you find your dv. Once you've picked u and dv this way, the steps are the same as above. Find du by differentiating u, and find v by integrating dv. Then use the IBP (integration by parts) formula and simplify for the answer.

      ILATE OR LIATE we can use both

    • ashish gupta 4 years ago

      @Anshul Kumar Which one to choose as “u” when you have log and inverse trig in the same problem?

    • Anshul Kumar 4 years ago

      @ashish gupta use ILATE in that case….but u will get same answer by LIATE too…..just a bit complex and some rearrangement needed😉

    • Rezaul Islam 4 years ago

      my math teacher in college used to joke 15 mins in a 45 min class. he one days explained the reason is: when a teacher teaches a complex thing to the class. the students brain concentration capacity keeps falling as time passes by. and sometime students will stop listening to him cz its not making any sense to them at all. so to recapture their attention and also to refresh their mind he would often pop jokes. he used to say that: if I lecure the whole 45 minutes and only 10 percent understands the whole thing then the whole 45 min is a waste. but if he can make us understand about 70 percent of what he said by joking for 15 minutes then the whole 45 minutes of the class is a success. not to mention all his jokes were phylosophical or real life based lessons wrapped in humour so those things teaching too which gives motivation to make us what we are today and helps a lot in the long run.

    I will be glad if you reply me soon ☺️

    • kumar upendra 3 years ago

      its simple… when there are 2 different functions in problems like one is algebraic and other trigonometric then you must have to use integration by parts only… always remember 2 different types of functions for integration by parts But there will be same type of functions for Integration by substitution … one function will be basic function and other will be its differentiation somehow…

    I tried x = ln(u) / e^x = u, and found dx/du = 1/u, which can be rearranged to give dx * e^x = du, which I could sub in to get int(ln(u))du, which ends up as = e^x*(x – 1) 😀 although traditionally to find int(ln(u)) you might need integration by parts anyways… 😀

  • Kxng Sauce 4 years ago

    Thanks for the video it was really good!!

    Btw do you write backwards or is it some mirror trick?

    • Teeban 4 years ago

      It’s backwards dude. 🙂

    • SweetSurrenderD 4 years ago

      She records it then mirrors the whole recording, look at her Q&A video it’s mirrored to this.

    • NuGanjaTron 3 years ago

      Mirroring makes sense considering she’s using her left hand here. But for reasons of orthogonality she should also talk backwards while showing us the reverse substitution. Oh, and the colours show be inverted too. ;^)

    Hii @NancyPi .. Integral of 1/(x²-6x+1)dx..can u please solve it.

    • thog 4 years ago

      ∫(x^2-6x+1)^-1dx, let u=x^2-6x+1, ∴du/dx = 2x-6 -> dx=1/(2x-6)du
      ∴∫(x^2-6x+1)^-1dx = ∫u^-1dx = 1/(2x-6)∫u^-1du
      1/(2x-6)∫u^-1du = 1/(2x-6)lnu + C
      = 1/(2x-6)ln(x^2-6x+1) + C

  • Evan 4 years ago

    Hey Nancy, love your videos but the bit at the end where you say that people don’t have to like maths is kinda pandering to the people that insist it’s not fun because they can’t do it. Maths is delayed gratification, which is why those that learn it are so in demand. Wish I’d been courageous enough to do it as my degree instead of wasting my time on computer science. Now I’m just doing it for fun.

  • Hanan Ahmed 4 years ago

    What is inverse trig ??

    • Gravity_Well 4 years ago

      sin^-1 or you see it as arcsign.

    • Warc Arden 4 years ago

      The inverse of the trigonometric functions. while the trigonometric functions give a ratio as output when an angle is given
      example: sin(45) = 1/sqrt(2)
      The inverse trigonometric functions are the reverse or rather the inverse. They take a ratio as input and give an angle as output.
      example: sin^-1(1/sqrt(2))= 45
      or simply if y= sinx
      then to find x or the angle we need the inverse of sine.
      thus x = sin ^ -1 (y)
      Very importantly, sin^-1(x) is NOT 1/sinx.
      1/sinx is cosecx or cscx. Inverse as in not multiplicative inverse but functional inverse if you have learnt inverse of a function before.

    • Warc Arden 4 years ago

      And they are also called the arcus functions or arcsin(x) arccos(x) etc to avoid the negative one power confusion with cosecx and secx

  • Lester Bernales 4 years ago

    what is the derivation and integration of e to the negative x?

    • Pasang sherpa 4 years ago

      Retsel Selanreb -e^x

    • Lester Bernales 4 years ago

      really?? how??? anyways thank u…

    • Warc Arden 4 years ago

      It is not -e^x, it is -e^-x or -1/e^x.
      We can do this with a couple ways.
      The first way is using the reverse chain rule.
      We know that integral of e raised to x is simply e raised to x +c .
      So e^-x is e^-x
      but as we know the derivative of -x is -1 and hence suppose when we differentiate e^-x we get -e^x which is -1 (e^x) thus we divide instead of multiplying in integration hence getting
      (e^-1)/-1 or -e^-x + c.

      The second way is using u sub. we let
      -x= u
      -dx = du
      dx = -du
      thus we get
      integral of – (e^u du)
      which is -e^u + c
      -e^-x+ c

    • Warc Arden 4 years ago

      Eustace Diem Both are correct and does not matter which one you use while its either one. Its just like BODMAS and BOMDAS, since multiplication and division are essentially the same thing so they are interchangeable. The inverse trigonometric functions and logarithmic functions are at the same ease of differentiablity

    • okie dokie 4 years ago

      @Warc Arden i got it. Thank u so much🙏🙏

  • 黃帟榳 4 years ago

    Dear Nancy, may I ask why integrate e^x equal to e^x

    • Ophnix 4 years ago

      Because the derivate of e^x is e^x . So if e^x is e^x dx ——- then the integration of e^x dx is e^x

      @Ophnix thank u

    Thank you. i’m doing some review for my calc 2 class next semester. One thing I would recommend is a time stamp or something so people who are refreshing for review don’t have to sit through the explanation. Maybe it’s just me but when I can’t remember and i’m watching a video that 2-3 minutes of “this is why we do it” or “why do we do it” is like nails on a chalkboard. Some need it, maybe even most need it. But i’m sure i’m not the only person just doing a refresher.

    Tips: Before integrating, you have to observe the given and ask yourself, what part in the integrand that you can differentiate and integrate. Example, xe^x. We can differentiate x we can also differentiate e^x, we can also integrate x we can also integrate e^x , so you can choose either of them and gives the same answer.

  • Morgel666 3 years ago

    That’s It E.T. back to the moon with you …

    Do you perhaps have something on integral parts about wave forms?
    I want to know something about Riemann Integral to take these different positions in calculus.
    With a better performance in Lebesgue Integral performance by parts in wave forms.

    I want to use it in demonstration of graphical approach in the visual aspect for graphics.
    Since every pixel is created as a color wave to represent color intensity to construct an image.
    I need to explain every frequency is divided in spectrum of colors for the image.
    Which in mathematical approach is the integral part of the spectrum in waveforms of the Fourier spectrum.

    Since every waveform has a complex domain in this spectrum. I need to take derivatives in time domain for the original pixel values.
    To express it for digital compression and integrals in frequency domain to get the spectral parts of the waveforms.

    Since every signalfunction in waveforms is divided towards Fourier transformation. it is either multiplied or divided in basic signalfunctions from cosinus waveforms and sinus waveforms.

    This gives the complex domain where eulers number comes fort to multiply or divide every spectral as a waveform function.
    Along side the unit circle in cosinus function or sinus function for the real parts and imaginary parts.

    The vectors of the waveforms explain the intensity of the pixel in value which gives us eventually the whole image projected as we visualise it.

    To understand this better for smoothening we used also Gauss function to get blurring effect as a filterimage.
    Were parts of Laplace transformation came in order to take different dimensions. for 1D, 2D or 3D images with 4D dimension along side color depth.

    Which gave more perspective in images for black and white, grayscale or color RGB in colordepth with transparancy towards alpha.

    I hope this is good conclusion on image frequency compression.

    Can you do a video of a multiple integration by parts example?

  • Kashvi Chabbra 2 years ago

    Why is the differentiation of e^x, e^x only and also the integration of e^x, e^x only…? Why not xe^x-1 or e^x+1/x+1???😕😟🤔🤔🤔

    Nooo. You have obtained great knowledge from MIT, and shouldn’t be wasting your time on such simple stuff. Many people can do a video on this. Please cover *calculus 3* !! I understand that the audience is going to be smaller, but still please consider it.
