What are examples of trigonometric functions?
Trigonometric functions are functions that relate an angle in a right angled triangle to the ratio of two of its sides. Sin , cos and tan are trigonometric functions.
What can be used to simplify integrals involving trigonometric functions?
Some integrals involving trigonometric functions can be evaluated by using the trigonometric identities. These allow the integrand to be written in an alternative form which may be more amenable to integration. On occasions a trigonometric substitution will enable an integral to be evaluated.
