integral from 6 to 8 of (28)/((x-6)^3)

\int_{6}^{8} \frac{28}{( x - 6 ) ^{3}} d x

diverges

Solution steps

\int_{6}^{8} \frac{28}{( x - 6 ) ^{3}} d x

Take the constant out:

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

= 28 \cdot \int_{6}^{8} \frac{1}{( x - 6 ) ^{3}} d x

Apply u-substitution

: \int_{0}^{2} \frac{1}{u ^{3}} d u

= 28 \cdot \int_{0}^{2} \frac{1}{u ^{3}} d u

Apply the Power Rule

: [- \frac{1}{2 u ^{2}}]_{0}^{2}

= 28 [- \frac{1}{2 u ^{2}}]_{0}^{2}

Compute the boundaries:

= diverges

\int r^{3} d r

\int \frac{2 x ^{2} + 5 x + 18}{x ( x ^{2} + 9 )} d x

(- 9, - 9), (- 6, 0)

7 \cdot 5^{x}

\frac{d}{d x} (5 x^{- 5})
