integral from 0 to 2 of (x^2+y^2)

\int_{0}^{2} (x^{2} + y^{2}) d x

2 y^{2} + \frac{8}{3}

Solution steps

\int_{0}^{2} x^{2} + y^{2} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{2} y^{2} d x + \int_{0}^{2} x^{2} d x

\int_{0}^{2} y^{2} d x = 2 y^{2}

\int_{0}^{2} x^{2} d x = \frac{8}{3}

= 2 y^{2} + \frac{8}{3}
