integral from-4 to 4 of sqrt(3)(16-x^2)

\int_{- 4}^{4} 3 (16 - x^{2}) d x

\frac{256}{3}

Decimal Notation

147.80166 \dots

Solution steps

\int_{- 4}^{4} 3 (16 - x^{2}) d x

Take the constant out:

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

= 3 \cdot \int_{- 4}^{4} 16 - x^{2} 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

= 3 (\int_{- 4}^{4} 16 d x - \int_{- 4}^{4} x^{2} d x)

\int_{- 4}^{4} 16 d x = 128

\int_{- 4}^{4} x^{2} d x = \frac{128}{3}

= 3 (128 - \frac{128}{3})

Simplify

3 (128 - \frac{128}{3}) : \frac{256}{3}

= \frac{256}{3}

\int_{0}^{2 π} 4 cos (x) d x

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

\int_{100}^{200} \frac{100}{x ^{2}} d x

\int_{0}^{\frac{π}{2}} \frac{1}{4} cos^{4} (x) d x

\int_{- 1}^{3} x + 3 d x
