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. Now, we can recognise sec^2(x) as the derivative of tan(x) (you can prove this using the quotient rule and the identity sin^2(x) + cos^2(x) = 1), while we get x when we integrate 1, so our final answer is tan(x) - x + c.

Any suggestions/advice on how I should proceed with this question? We have to integrate the following $$\int \tan x \tan 2x \tan 3x \,\mathrm dx$$ In this I tried as First split it into sine and cosine terms Then used $\sin 2x =2\sin x \cos x$ But after that 2020-12-30 Read It Watch It Talk to a Tutor 5.

This is a free utility available to 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. X Well begun is half done. You have joined No matter what your level.
