To find the derivative of sin(x) with respect to x, we can use the chain rule.
The chain rule states that if we have a composition of functions where y = f(g(x)), then the derivative of y with respect to x is given by (dy/dx) = (dy/dg) * (dg/dx).
In the case of sin(x), we can think of it as the composition of two functions: y = f(g(x)) = sin(x), where g(x) = x.
The derivative of sin(x) with respect to x can be found by differentiating each part of the composition separately.
First, we differentiate the outer function f(g(x)), which is sin(x). The derivative of sin(x) with respect to x is cos(x).
Second, we differentiate the inner function g(x), which is simply x. The derivative of x with respect to x is 1.
Using the chain rule, we multiply the derivatives:
(dy/dx) = (dy/dg) * (dg/dx) = cos(x) * 1 = cos(x).
Therefore, the derivative of sin(x) with respect to x is cos(x).
