Derivative of sin to a power
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 ... WebSo when you differentiate 3x^2, you really apply both the power rule and the constant multiple rule. First, the constant multiple rule tells us that the derivative of 3x^2 is 3 times the derivative of x^2. Then, the power rule tells us that the derivative of x^2 is 2x. Put those two together, and you get that the derivative of 3x^2 is 6x.
