Learn how to solve definite integrals problems step by step online. Integrate the function x+1e^x from 1 to 2. Expand the integral \int_{1}^{2}\left(x+1+e^x\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{1}^{2} xdx results in: \frac{3}{2}. The integral \int_{1}^{2}1dx results in: 1. The integral \int_{1}^{2} e^xdx results in: 4.670774.
