integral from 2 to 4 of-2/(x^2)

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

- \frac{1}{2}

Decimal

- 0.5

Solution steps

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

Take the constant out:

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

= - 2 \cdot \int_{2}^{4} \frac{1}{x ^{2}} d x

Apply the Power Rule

: [- \frac{1}{x}]_{2}^{4}

= - 2 [- \frac{1}{x}]_{2}^{4}

Compute the boundaries:

\frac{1}{4}

= - 2 \cdot \frac{1}{4}

Simplify

= - \frac{1}{2}

\int_{0}^{π} y sin (z) d x

\int_{0}^{1} s 1 - s^{2} d s

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

\int_{1}^{2} 1 + \frac{x ^{3}}{8} d x

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