Final answer to the problem
Step-by-step Solution
Learn how to solve power rule for derivatives problems step by step online. Find the derivative of cosh(3x)^2. The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}. Any expression to the power of 1 is equal to that same expression. Taking the derivative of hyperbolic cosine. The derivative of the linear function times a constant, is equal to the constant.
