Proof of derivative of sinx

• Derivative of sinx Proof

  The graph also shows why the derivative of cos(x) is –sin(x). The derivatives of the inverse trigonometric function follow a similar pattern to . While any function’s derivative can be proven via the method used above for normal trig functions, we will prove this one mathematically. A similar proof exists for every derivative.
