integral from 1 to 2 of (x^2)/4

\int_{1}^{2} \frac{x ^{2}}{4} d x

\frac{7}{12}

Decimal

0.58333 \dots

Solution steps

\int_{1}^{2} \frac{x ^{2}}{4} d x

Take the constant out:

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

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

Apply the Power Rule

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

= \frac{1}{4} [\frac{x ^{3}}{3}]_{1}^{2}

Compute the boundaries:

\frac{7}{3}

= \frac{1}{4} \cdot \frac{7}{3}

Simplify

= \frac{7}{12}

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

\int_{y}^{1} \frac{1}{y} d y

\int_{0}^{1} \frac{1}{9 x ^{2} + 6 x + 1} d x

\int_{2}^{6} \frac{1}{5 x + 6} d x

\int_{0}^{x} f (x - t) d t
