WebJan 15, 2006 · f""(x) = cos(x) 4th derivative. and it would repeat after this right... see the pattern for a given n the nth derivative of cosine x can only be one of those 4 choices right. so if n/4 has a remainder of 1 the nth derivative is -sin(x) if n/4 has a remainder of 2 the nth derivative is -cos(x) if n/4 has a remainder of 3 the nth derivative is ... WebThe Derivative of the Sine Function. d d x [ sin x] = cos x. Proof: Certainly, by the limit definition of the derivative, we know that. d d x [ sin x] = lim h → 0 sin ( x + h) − sin ( x) h. Recalling the trigonometric identity sin ( α + β) = sin α cos β + cos α sin β, we can replace the sin ( x + h) above to arrive at.
