$\int_{-1}^{1} x^3dx+\int_{-1}^{1}2dx$

Learn how to solve definite integrals problems step by step online. Integrate x^3+2 from -1 to 1. The integral of a sum of two or more functions is equal to the sum of their integrals. The integral \int_{-1}^{1} x^3dx results in: 0.25. The integral \int_{-1}^{1}2dx results in: 2. Gather the results of all integrals.
