integral from-2 to 0 of 3x^2

\int_{- 2}^{0} 3 x^{2} d x

8

Solution steps

\int_{- 2}^{0} 3 x^{2} d x

Take the constant out:

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

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

Apply the Power Rule

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

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

Compute the boundaries:

\frac{8}{3}

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

Simplify

= 8

\int_{0}^{1} sin^{2} (\frac{π}{6} x) d x

\int_{7}^{9} arctan (\frac{7}{x}) d x

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

\int_{4}^{25 - x^{2} - y^{2}} 1 d z

\int_{0}^{1} sin (x) (1 - x) d x
