Discover the Derivative of Sin(x) with Step-by-Step Guide

d/dx(sinx)

cosx

The derivative of sin(x) with respect to x is cosine(x).

We can prove this using the chain rule. The derivative of sin(x) can be written as:

dy/dx = dy/du * du/dx

where y = sin(x) and u = x.

Now, the derivative of y = sin(u) with respect to u is:

dy/du = cos(u)

and the derivative of u = x with respect to x is:

du/dx = 1

Therefore, the full derivative of sin(x) is:

dy/dx = dy/du * du/dx = cos(u) * 1 = cos(x)

So, the derivative of sin(x) with respect to x is cos(x).
