integral from 1 to 2 of-5/(x^2)

\int_{1}^{2} - \frac{5}{x ^{2}} d x

- \frac{5}{2}

Decimal

- 2.5

Solution steps

\int_{1}^{2} - \frac{5}{x ^{2}} d x

Take the constant out:

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

= - 5 \cdot \int_{1}^{2} \frac{1}{x ^{2}} d x

Apply the Power Rule

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

= - 5 [- \frac{1}{x}]_{1}^{2}

Compute the boundaries:

\frac{1}{2}

= - 5 \cdot \frac{1}{2}

Simplify

= - \frac{5}{2}

\int_{- 1}^{1} 3 x^{4} - x^{2} + x - 1 d x

\int_{0}^{4} (\frac{1}{2} x + 2) d x

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

\int_{0}^{1} 2 k x d x

\int_{0}^{2} (4 t - 1)^{10} d t
