integral from 0 to 0.4 of x^2

\int_{0}^{0.4} x^{2} d x

0.02133 \dots

Solution steps

\int_{0}^{0.4} x^{2} d x

Apply the Power Rule

: [\frac{x ^{3}}{3}]_{0}^{0.4}

= [\frac{x ^{3}}{3}]_{0}^{0.4}

Simplify

= [0.33333 \dots x^{3}]_{0}^{0.4}

Compute the boundaries:

0.02133 \dots

= 0.02133 \dots

\int_{0}^{1} 7 x^{3} d x

\int_{0}^{1} 9 x (x^{2} - 1)^{7} d x

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

\int_{- 2 π}^{2 π} 2 sin (x) d x

\int_{0}^{2} - 3 x^{2} + 6 x d x
