integral from 1 to 2 of (3x^2)/8

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

\frac{7}{8}

Decimal

0.875

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule

= \frac{3}{8} [\frac{x ^{3}}{3}]_{1}^{2}

Compute the boundaries:

\frac{7}{3}

= \frac{3}{8} \cdot \frac{7}{3}

Simplify

= \frac{7}{8}
