$20\int\tan\left(x\right)^3dx$
Learn how to solve trigonometric integrals problems step by step online. Solve the trigonometric integral int(20tan(x)^3)dx. The integral of a function times a constant (20) is equal to the constant times the integral of the function. Use trig identites to rewrite the integral's argument \tan\left(x\right)^3 in an expanded form. Expand the integral \int\left(\tan\left(x\right)\sec\left(x\right)^2-\tan\left(x\right)\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral 20\int\tan\left(x\right)\sec\left(x\right)^2dx results in: 10\sec\left(x\right)^2.
