integral of (e^t+2)/(e^t+2t)

\int \frac{e ^{t} + 2}{e ^{t} + 2 t} d t

ln e^{t} + 2 t + C

Solution steps

\int \frac{e ^{t} + 2}{e ^{t} + 2 t} d t

Apply u-substitution

= \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = e^{t} + 2 t

= ln e^{t} + 2 t

Add a constant to the solution

= ln e^{t} + 2 t + C
