integral from 0 to 2 of pi(1/(x+4))^2

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

\frac{π}{12}

Decimal Notation

0.26179 \dots

Solution steps

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

Simplify

(\frac{1}{x + 4})^{2} : \frac{1}{( x + 4 ) ^{2}}

= π \cdot \int_{0}^{2} \frac{1}{( x + 4 ) ^{2}} d x

Apply u-substitution

: \int_{4}^{6} \frac{1}{u ^{2}} d u

= π \cdot \int_{4}^{6} \frac{1}{u ^{2}} d u

Apply the Power Rule

: [- \frac{1}{u}]_{4}^{6}

= π [- \frac{1}{u}]_{4}^{6}

Compute the boundaries:

\frac{1}{12}

= π \frac{1}{12}

Simplify

= \frac{π}{12}

\frac{x ^{2}}{y ^{2} - 5} \frac{d y}{d x} = \frac{1}{2 y}

f (x) = ln (81 sin^{2} (x))

\frac{d}{d x} (\frac{2 x + 1}{3 x - 2})

x \to 3 lim (\frac{x - 3}{x - 2})

y = 7 x - x^{2}, (1, 6)
