integral from-2 to 2 of 16-4y^2

Solution

\int_{- 2}^{2} 16 - 4 y^{2} d y

Solution

\frac{128}{3}

+1

Decimal Notation

42.66666 \dots

Solution steps

\int_{- 2}^{2} 16 - 4 y^{2} d y

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 2}^{2} 16 d y - \int_{- 2}^{2} 4 y^{2} d y

\int_{- 2}^{2} 16 d y = 64

\int_{- 2}^{2} 4 y^{2} d y = \frac{64}{3}

= 64 - \frac{64}{3}

Simplify

64 - \frac{64}{3} : \frac{128}{3}

= \frac{128}{3}
