Law of Sines… How? When? (NancyPi)

MIT grad shows how to use the Law of Sines to solve a triangle for missing sides and angles. To skip ahead: 1) AAS or ASA case, when you're given TWO ANGLES AND A SIDE, skip to 0:17. 2) For how to know WHEN to use the Law of Sines in trigonometry, skip to 5:55. 3) For when the SSA ambiguous case comes up, and there may be one solution, two solutions, or no solution, skip to 6:32. Nancy formerly of MathBFF explains the trig steps to find the missing sides of a triangle using the sine function in this basic introduction to the Law of Sines formula used in trigonometry, geometry, algebra 2, and precalculus. This trig law is also known as the Sine Rule. It is helpful for solving OBLIQUE triangles with trigonometric functions. For help with and examples of solving a RIGHT triangle using trig functions, jump to https://youtu.be/a5WQlcFTXyk.

If you need to "solve the triangle" in a trigonometry problem, it just means to find all the missing angles and sides of the triangle.

WHAT is the LAW of SINES? Say that you're given an oblique triangle, meaning one that is not a right angle triangle, and you need to solve it. If you know two angles and at least one of the sides, you can solve with the Law of Sines trigonometry formula. The Law of Sines says that the sine of one angle over the side opposite that angle, equals the sine of the next angle over its opposite side, which equals sine of the last angle over its opposite length. These three ratios equal each other, and you can use these proportions to solve for unknowns.

Say that you're given that angle B is 34 degrees, angle C is 110 degrees, and side b is 14. We know two angles and one side. What's missing, or what we're looking for, is side a, side c, and the measure of angle A. That missing third angle, angle A, we can find very quickly without using any special new law or trig identity, since the sum of the degrees in a triangle is always 180 degrees. Subtracting the two known angles (34 and 110 degrees) from the total 180 degrees gives that the measure of angle A is 36 degrees.

HOW to use the Law of Sines: to find the missing two side lengths, we do need the Law of Sines theorem. First write all the ratios from the Law of Sines: the sine of each angle, over the length opposite. We write the sine of 36 degrees over the opposite side, side a. This equals sine of the next angle, 34 degrees, over its opposite side 14. And finally, that equals sine of the last angle, 110 degrees, over the opposite length, the unknown c.

If we look at just the leftmost two ratios, we see that we can use that equation to solve for a. So we separate that part out to solve: sin(36)/a = sin(34)/14. An easy way to solve a proportion like this is to cross-multiply. This gives us 14sin(36) = a*sin(34). Now it's more clear how to solve for side a, by just dividing out sin(34) from both sides. So we get that a is equal to 14*sin(36)/sin(34). To get a number value that's practical as the length of a triangle side, you can use your calculator to get a decimal number. CAUTION: since we were given angles in degrees, make sure your calculator is in degree mode, not radian mode, so that you don't get the wrong answer. The side length a is then approximately 14.72.

Now there's just one more unknown to find, the side c. To find the remaining missing side of a triangle, you can use a different pair of ratios to solve, the equation with the rightmost two ratios: sin(34)/14 = sin(110)/c. In general, to solve for one of the unknowns, use the ratio that has what you want to find in it, as the only unknown, and set it equal to a ratio where you know everything already, and you will get the answer. We cross-multiply to get c*sin(34) = 14sin(110). When we get c alone and use a calculator, we find that side length c is approx. 23.53. Now we've completely solved the triangle for all the missing sides and angles.

How do you know WHEN to use the LAW of SINES? If you're given two angles and a side (AAS or ASA cases), or two sides and an angle opposite one of those sides (SSA), you can use the Law of Sines property. If you have two angles and one side (AAS/ASA), you can use the Law of Sines just as we did to find the missing sides. WARNING: for the SSA case, when you have two sides and an angle that's opposite one of them, you can also use the Law of Sines to solve, but instead of having one solution, there may be no solution or two solutions. The SSA case is also called the "ambiguous case".

You turned me round from freezing in fear and not knowing what to do into someone who is actually happy to do maths.

    So good to see you back! I took calculus through differential equations in college 35 years ago and promptly stopped studying math when I started Medical School. For quite a while I have been rediscovering the beauty of math by re-learning the calculus, but occasionally stumble upon a huge gap in my memory of some basic concept once second nature to me all those years ago. This upsets me greatlyโ€”but when you happen to address the concept in one of your videos, your calm assuredness and straightforward presentations are so much appreciated. You are a superb teacher which in my line of work which is Medicine is the greatest complement I have to offer. Thank you again for the videos and welcome back. Steve K.

So far I have two math card games, and a series on integers, but have high school content planned for later this week. I am SUPER excited about my video going up tomorrow, which I think will make math fun for A LOT of people! I will be posting 3 videos a week and I would LOVE if you checked out my channel ๐Ÿ™‚

    Thanks, like your new sereis. Your’e not so intense now and a little more relaxed. When you started out, I was super paranoid of you, as In a former existence in another star system, I was a highly placed official. A type of general. They made a clone that was a killer, betrayer, and how you would tell these part from normal people, is they had no nivea’s on their bodies. So I looked and looked for a beauty spot on you and found one. When I did, I could finally relax. Good sereis. You take the difficult in math making it more than one dimension and therefore digestable. Thank you, wish you continued success.

    Hi Nancy,
    Can you show me the math that allows you to have stopped the ageing process?
    Your face and skin are apparently not following the mathematical norms of getting older.
    You’re not only a great mathematician, but a rather attractive one to boot.
    Which reminds me of a famous quote, “To boot or not to boot, that is the hardest drive.”

    Just saying,

I find your teaching style quite comfortable and would appreciate it if you considered quadratics as a tutorial.

    I wonder, does people here notice the great work you’ve been doing to realize these simple, concise, yet thorough explanations? And did anybody realize that the video must have been flipped horizontally, to be read correctly, and that we are seeing the horizontally-reflected version of your figure? Just wondering.

    These trig formulas are extremely valuable in the building trade. Not all angles are right triangles. Knowing this stuff saves you from holding up heavy pieces of lumber (or steel) and marking the angle, or taping the lengths while leaning out over a thirty foot roof. Give it a try, thanks for the video.

    Hi Nancy. Have you ever looked at Big O notation in regards to computer science? Everyone is soooo bad at explaining it. Basically it boils down to calculating runtime and memory cost of a function.

    Not sure if you could do a series on it, but since you’re obviously good at math, there’s really not any “code” going on at all. Simply all theoretical math. I bet it would get a ton of views.

    GREAT work as usual.. love your videos. I am required to teacher some of my math classes online starting in September “thank you COVID 19” and i am interested in the writing system you are using. So far i think it’s the one that will work best for me. Can you share what it is and or how to set one up?

    Dear NancyPi,
    I am taking Calculus 2. Can you please make a video about disks and washers and when to use either. Also can you please do 4 problems? Problem 1, disks about the x-axis. Problem 2 same problem, but this time about the y-axis. Problem 3, washers about the x-axis and Problem 4 the same one, but about the y-axis. You don’t have to solve them. I just have trouble setting up the problem. The integration is the easy part. The hard part is the setup. Please dumb it down as much as possible. This is the 2nd time I take Calculus 2 and I still do not understand it.
