integral from 1 to 3 of 7/(x^2)

\int_{1}^{3} \frac{7}{x ^{2}} d x

\frac{14}{3}

Decimal Notation

4.66666 \dots

Solution steps

\int_{1}^{3} \frac{7}{x ^{2}} d x

Take the constant out:

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

= 7 \cdot \int_{1}^{3} \frac{1}{x ^{2}} d x

Apply the Power Rule

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

= 7 [- \frac{1}{x}]_{1}^{3}

Compute the boundaries:

\frac{2}{3}

= 7 \cdot \frac{2}{3}

Simplify

= \frac{14}{3}

\frac{d}{d t} (y + v (t) \cdot t + (\frac{a}{2}) \cdot t^{2})

\int_{0}^{2} x 2 - x d x

\frac{d}{d x} ((8 x + 5) (x^{2} - 3 x))

\frac{d}{d x} (\frac{e ^{x}}{1 + x ^{2}})

\int_{1}^{6} \frac{2}{x ^{3}} d x
