How do you integrate trigonometric functions?

Problem Statement

How do you integrate trigonometric functions?

Step-by-Step Explanation

Integrating trigonometric functions uses identities, substitution, and known antiderivatives.

1. Identify what the question is asking. In Calculus 2, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
3. Work one step at a time and keep units, signs, and restrictions visible.
4. Check whether the answer makes sense in the original context.

Final Answer

Integrating trigonometric functions uses identities, substitution, and known antiderivatives. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
