integral of (y^2-1)

Solution

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

Solution

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

Solution steps

\int y^{2} - 1 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 y^{2} d y - \int 1 d y

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

\int 1 d y = y

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

Add a constant to the solution

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