integral of pi(x+2)^2

\int π (x + 2)^{2} d x

π (\frac{x ^{3}}{3} + 2 x^{2} + 4 x) + C

Solution steps

\int π (x + 2)^{2} d x

Take the constant out:

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

= π \cdot \int (x + 2)^{2} d x

Expand

(x + 2)^{2} : x^{2} + 4 x + 4

= π \cdot \int x^{2} + 4 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

= π (\int x^{2} d x + \int 4 x d x + \int 4 d x)

\int x^{2} d x = \frac{x ^{3}}{3}

\int 4 x d x = 2 x^{2}

\int 4 d x = 4 x

= π (\frac{x ^{3}}{3} + 2 x^{2} + 4 x)

Add a constant to the solution

= π (\frac{x ^{3}}{3} + 2 x^{2} + 4 x) + C

f (x) = x + 63, (1, 8)

\int_{0}^{1} t 1 + 4 t^{2} d t

x y^{^{'}} = y + e^{\frac{y}{x}}

x \to 2 lim (- 2)

\frac{d x}{d t} = x sin (t), x (0) = 1
