Law of Cosines, Finding Angles & Sides, SSS & SAS Triangles - Trigonometry

This trigonometry video tutorial provides a basic introduction into the law of cosines. It explains how to use the law of cosines formula for finding angles and for finding the value of missing sides. It explains how to solve the sss triangle and the sas triangle using the law of cosines first and then finishing up the problem using the law of sines formula. This trig video contains plenty of examples and practice problems.

how did he convert to degrees? I know how to convert with pi/180 to radians but got something different. At what part did he convert?

[@Yellowbrick559]

There are a ton of math tutorial videos on TH-cam, but there is something about the way you explain things and the calming presence of your voice that makes it so much easier to understand. I always watch multiple videos on the same subject only to find yours and things finally click. Thanks so much for what you do!

[@mareksogars2954]

I’m so confused, on the last question i found A first, which was infact 48.2 degrees, but then i got B = 40.5 and C = 91.3, all of which added together = 180. I’ve skimmed through my working and can’t find anything wrong

is it possible to still use the cosine rule all through to get the same answers

thank you thank you thank you!

What if u r trying to find cos a or b how do u set ur the equation

[@baker7280]

Same way, just plug in the values you know and solve.
