integral from 0 to a of a^2x-x^3

\int_{0}^{a} a^{2} x - x^{3} d x

\frac{a ^{4}}{2} - \frac{a ^{4}}{4}

Solution steps

\int_{0}^{a} a^{2} x - x^{3} 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}^{a} a^{2} x d x - \int_{0}^{a} x^{3} d x

\int_{0}^{a} a^{2} x d x = \frac{a ^{4}}{2}

\int_{0}^{a} x^{3} d x = \frac{a ^{4}}{4}

= \frac{a ^{4}}{2} - \frac{a ^{4}}{4}

\int_{0}^{x} 2 t cos (t) d t

\int_{0}^{1} 8 x e^{x} d x

\int_{- π}^{π} a sin (θ) d θ

\int_{0}^{6} x^{2} - 9 d x

\int_{0}^{π} sin^{2} (d) x d x
