integral of ((e^{2x}))/(e^{2x)+5}

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

\frac{1}{2} ln e^{2 x} + 5 + C

Solution steps

\int \frac{e ^{2 x}}{e ^{2 x} + 5} d x

Apply u-substitution

: \int \frac{1}{2 u} d u

= \int \frac{1}{2 u} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{2} ln ∣ u ∣

Substitute back

u = e^{2 x} + 5

= \frac{1}{2} ln e^{2 x} + 5

Add a constant to the solution

= \frac{1}{2} ln e^{2 x} + 5 + C

\int \frac{x ^{2}}{( 2 x - 1 ) ^{2}} d x

\int x lo g_{3} (x^{2}) d x

\int (- \frac{9}{x ^{4}}) d x

\int 6 x^{3} e^{- 5 x} d x
