integral from-1 to 1 of 2y^2

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

\frac{4}{3}

Decimal

1.33333 \dots

Solution steps

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

Take the constant out:

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

= 2 \cdot \int_{- 1}^{1} y^{2} d y

Apply the Power Rule

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

Compute the boundaries:

\frac{2}{3}

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

Simplify

= \frac{4}{3}
