Derivative sin x proof
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. WebDerivative Proofs. Though there are many different ways to prove the rules for finding a derivative, the most common way to set up a proof of these rules is to go back to the …
