Various exercises relating to the integration of trigonometric functions.

Compute the indefinite integrals below. Since there are many possible answers (which differ by constant values), use the given instructions if needed to choose which possible answer to use.
(Your answer should not include any constant term.)
(Your answer should not include any constant terms.)
(Add a constant to your answer if needed so that it equals at .)
(Add a constant to your answer if needed so that it equals at .)
(Your answer should not include any constant terms.)
You can either use an integration by parts technique or you can use a trigonometric identity to simplfy the expression (for constants and ) as a sum of simpler things.
(Your answer should not include any constant terms.)
(Your answer should not include any constant terms and should equal at .)
Use power reduction formulas.
To fully evaluate the integral from Example trig:reduce_example, it helps to identify the pattern. Suppose that the power is replaced by an unknown positive constant . Carry out the calculation again with the unspecified exponent: We conclude Using this formula several times in a row gives the result
