integral from 0 to 7 of (3t)/((t-8)^2)

\int_{0}^{7} \frac{3 t}{( t - 8 ) ^{2}} d t

3 (- 3 ln (2) + 7)

Decimal Notation

14.76167 \dots

Solution steps

\int_{0}^{7} \frac{3 t}{( t - 8 ) ^{2}} d t

Take the constant out:

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

= 3 \cdot \int_{0}^{7} \frac{t}{( t - 8 ) ^{2}} d t

Apply u-substitution

: \int_{- 8}^{- 1} \frac{u + 8}{u ^{2}} d u

= 3 \cdot \int_{- 8}^{- 1} \frac{u + 8}{u ^{2}} d u

Expand

\frac{u + 8}{u ^{2}} : \frac{1}{u} + \frac{8}{u ^{2}}

= 3 \cdot \int_{- 8}^{- 1} \frac{1}{u} + \frac{8}{u ^{2}} d u

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_{- 8}^{- 1} \frac{1}{u} d u + \int_{- 8}^{- 1} \frac{8}{u ^{2}} d u)

\int_{- 8}^{- 1} \frac{1}{u} d u = - 3 ln (2)

\int_{- 8}^{- 1} \frac{8}{u ^{2}} d u = 7

= 3 (- 3 ln (2) + 7)

f (x) = \frac{2}{3 x + 5}, at a = - 1

\int_{0}^{4} π (4 x - x^{2}) d x

x sin (- 2 x) π

9 y^{^{''}} - 7 y = 0
