Step 1: Recognize that the integral involves trigonometric functions raised to powers. To simplify, use trigonometric identities. For example, sin²(x) can be expressed as (1 - cos²(x)) using the Pythagorean identity.
Step 2: Rewrite the integral in terms of a single trigonometric function, such as cos(x). Substitute sin²(x) = (1 - cos²(x)) into the integral to simplify the expression.
Step 3: Use substitution to simplify further. Let u = cos(x), then du = -sin(x) dx. Replace cos(x) and sin(x) terms in the integral with u and du.
Step 4: After substitution, the integral will be in terms of u. Simplify the resulting polynomial expression and integrate term by term.
Step 5: Once the integration is complete, substitute back u = cos(x) to return to the original variable. Add the constant of integration, c, to finalize the solution.
