integral from-2 to 2 of 1/2 (16-x^4)

\int_{- 2}^{2} \frac{1}{2} (16 - x^{4}) d x

\frac{128}{5}

Decimal

25.6

Solution steps

\int_{- 2}^{2} \frac{1}{2} (16 - x^{4}) d x

Take the constant out:

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

= \frac{1}{2} \cdot \int_{- 2}^{2} 16 - x^{4} d x

Apply the Sum Rule:

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

= \frac{1}{2} (\int_{- 2}^{2} 16 d x - \int_{- 2}^{2} x^{4} d x)

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

\int_{- 2}^{2} x^{4} d x = \frac{64}{5}

= \frac{1}{2} (64 - \frac{64}{5})

Simplify

\frac{1}{2} (64 - \frac{64}{5}) : \frac{128}{5}

= \frac{128}{5}
