In 1–26, find the indicated indefinite integral.

SolutionStep 1 of 7In this problem we have to integrate the given indefinite integral, Let us takeI = Step 2 of 7There are 2 functions multiplied with each other, Following ILATE Rule (Inverse trigonometric, Logarithmic, Algebraic, Trigonometric, and Exponential) we proceed solving as follows.Step 3 of 7Since is a polynomial, cos() is Trigonometric, by ILATE rule we take First function as and Second Function as Step 4 of 7Differentiating the first function and integrating the second function we get and
