The derivative of the sine of a function is equal to the cosine of that function times the derivative of that function, in other words, if ${f(x) = \sin(x)}$, then ${f'(x) = \cos(x)\cdot D_x(x)}$

Learn how to solve basic differentiation rules problems step by step online. Find the derivative of sin(-x). The derivative of the sine of a function is equal to the cosine of that function times the derivative of that function, in other words, if {f(x) = \sin(x)}, then {f'(x) = \cos(x)\cdot D_x(x)}. The derivative of a function multiplied by a constant (-1) is equal to the constant times the derivative of the function. The derivative of the linear function is equal to 1. Expand and simplify.
