integral from 0 to 1 of (2t)/((2-t)^2)

\int_{0}^{1} \frac{2 t}{( 2 - t ) ^{2}} d t

2 (1 - ln (2))

Decimal

0.61370 \dots

Solution steps

\int_{0}^{1} \frac{2 t}{( 2 - t ) ^{2}} d t

Take the constant out:

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

= 2 \cdot \int_{0}^{1} \frac{t}{( 2 - t ) ^{2}} d t

Apply Integration By Parts

= 2 [\frac{t}{2 - t} - \int \frac{1}{2 - t} d t]_{0}^{1}

\int \frac{1}{2 - t} d t = - ln ∣ 2 - t ∣

= 2 [\frac{t}{2 - t} - (- ln ∣ 2 - t ∣)]_{0}^{1}

Simplify

= 2 [\frac{t}{2 - t} + ln ∣ 2 - t ∣]_{0}^{1}

Compute the boundaries:

1 - ln (2)

= 2 (1 - ln (2))
