integral from 0 to 8 of pi(x+1)^2

\int_{0}^{8} π (x + 1)^{2} d x

π \frac{728}{3}

Decimal Notation

762.35981 \dots

Solution steps

\int_{0}^{8} π (x + 1)^{2} d x

Take the constant out:

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

= π \cdot \int_{0}^{8} (x + 1)^{2} d x

Expand

(x + 1)^{2} : x^{2} + 2 x + 1

= π \cdot \int_{0}^{8} x^{2} + 2 x + 1 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

= π (\int_{0}^{8} x^{2} d x + \int_{0}^{8} 2 x d x + \int_{0}^{8} 1 d x)

\int_{0}^{8} x^{2} d x = \frac{512}{3}

\int_{0}^{8} 2 x d x = 64

\int_{0}^{8} 1 d x = 8

= π (\frac{512}{3} + 64 + 8)

Simplify

π (\frac{512}{3} + 64 + 8) : π \frac{728}{3}

= π \frac{728}{3}

\int sin^{\frac{1}{2}} (2 z) cos^{3} (2 z) d z

(2)^{^{'}}

\int (8 x^{3} + \frac{1}{x}) d x

x \to - \infty lim (8 e^{x + 9})

f (x) = 3 e^{3 e^{x} + x}
