By recognizing the relationship between the trigonometric functions and using the derivative of cot\u2061(x)\\cot(x)cot(x), we were able to transform the integral into a more straightforward form, which was then solved using basic integration rules. The constant of integration CCC accounts for the fact that the integral represents a family of functions, all differing by a constant.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner5-729.jpeg\" alt=\"\" class=\"wp-image-245839\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Find the indefinite integral.
