integral from-7 to 7 of x^2

\int_{- 7}^{7} x^{2} d x

\frac{686}{3}

Decimal

228.66666 \dots

Solution steps

\int_{- 7}^{7} x^{2} d x

Apply the Power Rule

= [\frac{x ^{3}}{3}]_{- 7}^{7}

Compute the boundaries:

\frac{686}{3}

= \frac{686}{3}

\int_{0}^{2 π} - 7 sin^{2} (t) d t

\int_{0}^{1} 4 e^{x} d x

\int_{12}^{x} \frac{1}{t} d t

\int_{0}^{1} 4 x (x^{2} + 2)^{3} d x

\int_{- 1}^{0} 6 x^{2} (2 x^{3} + 4)^{2} d x
