Integration of TRIGONOMETRIC functions
1. Given an integral , i.e. the integrand is a rational function in terms of and . By the substitution the integral is reduced to an integral of a rational function. If , then , , and . 2. If = , then . 3. If = - , then . If =- , then . 4. , т and п – even non-negative integers, then , . 5. For integrals we use following formulas: 6. , then and .
