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

= \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

\int 3 x + 3 d x

\int \frac{6 - 4 x e ^{x}}{x} d x

8 x^{2}

\int \frac{- 2 x ^{3}}{x ^{3} + 1} d x

\int 8 x (4 x^{2} + 5)^{4} d x
