\int_{4}^{9} \frac{1}{x ^{2}} d x

\frac{5}{36}

Decimal

0.13888 \dots

Solution steps

\int_{4}^{9} \frac{1}{x ^{2}} d x

Apply the Power Rule

= [- \frac{1}{x}]_{4}^{9}

Compute the boundaries:

\frac{5}{36}

= \frac{5}{36}

\int_{- 8}^{8} x^{3} d x

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

\int_{0}^{2} 7 x (x^{2} + 1)^{2} d x

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

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