integral from-1 to 1 of x^2 1/2

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

\frac{1}{3}

Decimal Notation

0.33333 \dots

Solution steps

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

Apply the Power Rule

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

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

Compute the boundaries:

\frac{2}{3}

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

Simplify

= \frac{1}{3}

\int_{- 1}^{1} 8 - 2 x^{2} d x

\int_{2}^{4} x^{2} - 2 x - 8 d x

\int_{0}^{2} t^{3} 3 t^{2} + 1 d t

\int_{0}^{1} 16 x^{3} d x

\int_{6}^{\infty} 2 x^{- 3} d x
