Omar Badran. At which points are the tangents of cos x and sin x parallel? Now we explore the intuition behind the derivatives of trigonometric functions, discovering that the derivative of sin x is cos x and the derivative of cos x is -sin x. Regarding the unit circle, when sin is 0 cos is 1 or Flag Button navigates to signup page. And it is indeed the case that the derivative of sine of x is equal to cosine of x. If that is the case, then in our derivative function when x is equal to zero that derivative function should be equal to one. April 23, am.
