integral from 3 to 9 of x^2

\int_{3}^{9} x^{2} d x

234

Solution steps

\int_{3}^{9} x^{2} d x

Apply the Power Rule

: [\frac{x ^{3}}{3}]_{3}^{9}

= [\frac{x ^{3}}{3}]_{3}^{9}

Compute the boundaries:

234

= 234

\int_{1}^{6} t^{2} - 2 t - 15 d t

\int_{0}^{y} 2 z d z

\int_{0}^{1} 4^{5 x} d x

\int_{1}^{2} \frac{x - 1}{( 2 x - 1 ) ^{2}} d x

\int_{0}^{π} sin^{2} (x) cos (n x) d x
