Problem to solve:
$\int_{\left(2\right)\left(-1\right)}^{1}\left(x^2+1\right)dx$
Specify the solving method
1
Expand the integral $\int_{-2}^{1}\left(x^2+1\right)dx$ into $2$ integrals using the sum rule for integrals, to then solve each integral separately
$\int_{-2}^{1} x^2dx+\int_{-2}^{1}1dx$

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