$\int\frac{2\cos\left(x\right)^3}{1}dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (2cos(x)^3)/1. Find the integral. Any expression divided by one (1) is equal to that same expression. The integral of a function times a constant (2) is equal to the constant times the integral of the function. Apply the formula: \int\cos\left(\theta \right)^ndx=\frac{\cos\left(\theta \right)^{\left(n-1\right)}\sin\left(\theta \right)}{n}+\frac{n-1}{n}\int\cos\left(\theta \right)^{\left(n-2\right)}dx, where n=3.
