Derivative of cos theta 2

WebAs MJD suggests in the comments, we need to use the chain rule which basically states that: outside → f ( g ( x) ⏟ inside) = [ derivative of the outside evaluated at the inside] × [ derivative of the inside] We know that: d d x cos ( x) = − sin ( x) and d d x x 3 = 3 x 2. So by the chain rule: d d x cos 3 ( x) = d d x [ cos ( x ... Websatisfying x2 + y2 = 1, we have cos2 + sin2 = 1 Other trignometric identities re ect a much less obvious property of the cosine and sine functions, their behavior under addition of angles. This is given by the following two formulas, which are not at all obvious cos( 1 + 2) =cos 1 cos 2 sin 1 sin 2 sin( 1 + 2) =sin 1 cos 2 + cos 1 sin 2 (1)
