That is just blind memorization. Whenever I need to use cosine law to find the third side of a triangle opposite to an angle (Say A) I think of it more as a 'Find the hypotenuse ' problem except the hypotenuse is opposite to the angle A instead of 90°. This makes more sense to me and I can setup the problem correctly without any doubt.

Dear Jensen, thank you for your efforts. As a teacher myself, I understand the work behind this awesome teaching. Can I ask you which teaching tool are you using. For instance @ 3:40 (must know number 2) you were able to scale the right angle triangle without scaling anything else on the screen. FYI, I use ppt and various transitions for the animation effect. Pls. shed some light Thanks 🙂

It has been a while since i have done trig and was looking to brush up. @ around 8:08 - 8:50, you got approxametly 50.8 degrees. I got around 42 degrees. This comes to A = Cos^1(-283/-384) which = aprox .7422 rad or 42.5 degrees. Am I wrong?

I must be missing something. I have a triangle with known angles, 90 60 and 30, and a single known side length of 3 between the right angle and the 30. If the 30 is the reference angle, 3 is the Adjacent side therefore 3=a. I want to solve for the Hypotenuse, so h=x. I try to apply sine law. x is the hypotenuse, and the angle opposite the adjacent is 60, so x/sin(90) = 3/sin(60). Some balancing and x = 3sin(90) / sin(60) Which comes out to approx. -8.799 Which does not look even slightly correct. Just eyeballing my triangle, the hypotenuse should be slightly more than 3. I almost expect it to come out to pi. It should not be more than double the length of the known side and also negative. What am I doing wrong?
@jseries101
@jseries101 10 күн бұрын
You are correct about the answer being a little more than 3. I'm no math wizard. I learned a much more simple approach to trig. From my limited understanding though, you would want to choose Cosine to work with. The SOH, CAH, TOA choice is determined by which corner you are working from and the results you need to know. Working from the 1) 30° corner , 2) you know the adjacent side, 3) you want to know the Hypotenuse. You choose to use CAH since this formula uses both the known side(Adjacent) and the unknown (Hypotenuse) side. Plug this into your calculator and you will get the number you suspect.....hope this helps you.

Must Know #1: I'd have simply said that because lines BC and DE are parallel, just know that BC / DE (which is 10 /4) would tell me the ratio (or the multiplier to use). So, 10 / 4 is 2.5, that's the multiplier to use on line DA (which is 6) to work out the length of line BA. So, 6x2.5 = 15. We know the long line DA is x +6 , and we know the length is 15, so x = 15-6, which is 9. It takes longer to explain it to actually do it as you can do it in literally seconds!
