integral from 2 to 3 of r^{-3}

\int_{2}^{3} r^{- 3} d r

\frac{5}{72}

Decimal

0.06944 \dots

Solution steps

\int_{2}^{3} r^{- 3} d r

Apply the Power Rule

: [- \frac{1}{2 r ^{2}}]_{2}^{3}

= [- \frac{1}{2 r ^{2}}]_{2}^{3}

Compute the boundaries:

\frac{5}{72}

= \frac{5}{72}

\int_{1}^{x} (1 - t) d t

\int_{0}^{π} (2 + cos (x))^{2} d x

\int_{3}^{4} (x^{2} - x - 6) d x

\int_{2 x}^{10} cos (y^{2}) d y

\int_{- \frac{π}{2}}^{\frac{π}{2}} cos^{2} (u) d u
