$\int\frac{\sin\left(x\right)^2}{1+\cos\left(x\right)}dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (sin(x)^2)/(1+cos(x)). Find the integral. Rewrite the trigonometric expression \frac{\sin\left(x\right)^2}{1+\cos\left(x\right)} inside the integral. Expand the integral \int\left(1-\cos\left(x\right)\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int1dx results in: x.
