Unlock this full step-by-step solution!

Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(4*x*sec(x)^2)dx. The integral of a constant by a function is equal to the constant multiplied by the integral of the function. We can solve the integral \int x\sec\left(x\right)^2dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du. Now, identify dv and calculate v.

Final Answer

$4x\tan\left(x\right)+4\ln\left|\cos\left(x\right)\right|+C_0$
