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

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

\frac{3}{2}

Decimal

1.5

Solution steps

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

Apply the Power Rule

= 3 [- \frac{1}{x}]_{1}^{2}

Compute the boundaries:

\frac{1}{2}

= 3 \cdot \frac{1}{2}

Simplify

= \frac{3}{2}
