integral from 1 to 3 of-3/(x^2)

\int_{1}^{3} - \frac{3}{x ^{2}} d x

- 2

Solution steps

\int_{1}^{3} - \frac{3}{x ^{2}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 3 \cdot \int_{1}^{3} \frac{1}{x ^{2}} d x

Apply the Power Rule

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

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

Compute the boundaries:

\frac{2}{3}

= - 3 \cdot \frac{2}{3}

Simplify

= - 2

\int_{- 3}^{2} 2 x^{3} - 4 x d x

\int_{- 7}^{0} (1 + 49 - x^{2}) d x

\int_{4}^{7} \frac{2 x}{8 - x} d x

\int_{x}^{0} e^{- 10 t} d t

\int_{0}^{1} cos (w x) d x
