integral of (1+y^2)

Solution

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

Solution

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

Solution steps

\int 1 + y^{2} d y

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 y + \int y^{2} d y

\int 1 d y = y

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

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

Add a constant to the solution

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