How do you find the integral of (sec^2 x)(tan^2 x) dx? Calculus Techniques of Integration Integration by Parts 1 Answer Akshat Jun 22, 2018 (tan^3x)/3+C Explanation: By making a substitution, tanx= U, you will get dU = sec^2xdx. Therefore, dx= (dU)/sec^2x. Then the integral will become: intU^2dU. Substitute the value of U and obtain the result. Answer link Related questions How do I find the integral int(x*ln(x))dx ?
