To differentiate cos (2x), we can use the chain rule and the power rule. We can rewrite cos (2x) as (cos x)^2 and then apply the chain rule to get -2sin (2x).

No, the power rule cannot be used to differentiate cos x. The power rule is only applicable to functions of the form y = x^n, whereas the cosine function is a trigonometric function.

The derivative of cos x is -sin x. This can be proven using the chain rule and the power rule of differentiation.

Differentiating the cosine function involves applying the power rule and the chain rule of differentiation. The power rule states that if y = x^n, then y' = nx^(n-1). The chain rule states that if y = f(u) and u = g(x), then y' = f'(u) * g'(x). When differentiating the cosine function, we can use the chain rule to rewrite it as the derivative of the sine function.
