How to split up cosine
Weba² = b² + c² - 2bx All you need to do now is get rid of the letter x. This is done by using basic trigonometry in the triangle AND. Since CosѲ = adjacent/hypotenuse, then x can be expressed as: x = cCosA So the final step is to substitute x = cCosA into a² = b² + c² - 2bx: a² = b² + c² - 2bcCosA (just change x to cCosA) Web1. Add a comment. 4. 1. sin 4 ( x) = ( 1 − cos 2 ( x)) 2 = ( 1 − cos ( 2 x) 2) 2 = 1 4 − cos ( 2 x) 2 + cos 2 ( 2 x) 4. hence: sin 4 ( x) = 3 8 − cos ( 2 x) 2 + cos ( 4 x) 8 3 − 4 cos ( 2 x) + cos ( 4 x) 8. I have just applied the Pythagorean theorem ( sin 2 z + cos 2 z = 1) and twice the cosine duplication formula ( cos ( 2 z) = 2 ...
