integral of (1+x^2)

Solution

\int (1 + x^{2}) d x

Solution

x + \frac{x ^{3}}{3} + C

Solution steps

\int 1 + x^{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 1 d x + \int x^{2} d x

\int 1 d x = x

\int x^{2} d x = \frac{x ^{3}}{3}

= x + \frac{x ^{3}}{3}

Add a constant to the solution

= x + \frac{x ^{3}}{3} + C
