Problem 72E

Rational functions of trigonometric functions An integrand with trigonometric functions in the numerator and denominator can often be converted to a rational integrand using the substitution u =tan (x/2) or x = 2 tan?1 u. The following relations are used in making this change of variables.A: B: C: Verify relation A by differentiating x =2tan?1 u. Verify relations B and C using a right-triangle diagram and the double-angle formulas

Step-by-Step Solution:
