integral from-2 to 2 of 5x^2

\int_{- 2}^{2} 5 x^{2} d x

\frac{80}{3}

Decimal Notation

26.66666 \dots

Solution steps

\int_{- 2}^{2} 5 x^{2} d x

Take the constant out:

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

= 5 \cdot \int_{- 2}^{2} x^{2} d x

Apply the Power Rule

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

= 5 [\frac{x ^{3}}{3}]_{- 2}^{2}

Compute the boundaries:

\frac{16}{3}

= 5 \cdot \frac{16}{3}

Simplify

= \frac{80}{3}

\int_{0}^{2 π} cos^{5} (x) sin (x) d x

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

\int_{0}^{2} 4 - x d x

\int_{0}^{2} - g \cdot cos (n \cdot π \cdot g) d g

\int_{- 1}^{2} y^{2} + 4 d y
