Find the square root of 9801 by long division How to solve: Integrate. \int \tan^2x \sec x dx By signing up, you'll get thousands of step-by-step solutions to your homework questions. You can Get the answer to Integral of tan(x)^2 with the Cymath math problem solver - a free math equation solver and math solving app for calculus and algebra. 2020-03-25 · The integral of tan(x) can be solved by rewriting the equation as the integral of sin(x)/cos(x) dx, and then using the integration technique called substitution. Using substitution, the value u is used in place of sin(x), and the value for the derivative of u, du, is found to be -sin(x) dx.

Using the substitution. We now write our integral as.

This is a question which tests your knowledge of how to use trigonometric identities as well as integration. As there is no way to immediately integrate tan^2(x) using well known trigonometric integrals and derivatives, it seems like a good idea would be writing tan^2(x) as sec^2(x) - 1.
