integral from 0 to 3 of 1/2 x

\int_{0}^{3} \frac{1}{2} x d x

\frac{9}{4}

Decimal

2.25

Solution steps

\int_{0}^{3} \frac{1}{2} x d x

Take the constant out:

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

= \frac{1}{2} \cdot \int_{0}^{3} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{0}^{3}

= \frac{1}{2} [\frac{x ^{2}}{2}]_{0}^{3}

Compute the boundaries:

\frac{9}{2}

= \frac{1}{2} \cdot \frac{9}{2}

Simplify

= \frac{9}{4}

\int_{0}^{8} (3 x)^{2} d x

\int_{0}^{π} sin^{3} (φ) d φ

\int_{0}^{\frac{2}{3}} 1 + 36 x d x

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

\int_{0}^{\frac{1}{4}} y arctan (4 y) d y
