Let us assume y= cos-1 x. Differentiate Implicitly-sin y dy/dx= -1————-(i) By trigonometric identity we know that We can find the derivatives of sin x and cos x by using the definition of derivative and the limit formulas found earlier. The results are $\dfrac{d}{dx}\sin x=\cos x\dfrac{d}{dx}\cos x=−\sin x$. With these two formulas, we can determine the derivatives of all six basic trigonometric functions.
