integral of (e^x)/((4-e^x)^2)

\int \frac{e ^{x}}{( 4 - e ^{x} ) ^{2}} d x

\frac{1}{4 - e ^{x}} + C

Solution steps

\int \frac{e ^{x}}{( 4 - e ^{x} ) ^{2}} d x

Apply u-substitution

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

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

Take the constant out:

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

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

Apply the Power Rule

: - \frac{1}{u}

= - (- \frac{1}{u})

Substitute back

u = 4 - e^{x}

= - (- \frac{1}{4 - e ^{x}})

Simplify

= \frac{1}{4 - e ^{x}}

Add a constant to the solution

= \frac{1}{4 - e ^{x}} + C

\int \frac{3 x + 6}{2 x ^{2} + 8 x + 3} d x

x \to \frac{π}{4} lim (2 cot (2 x))

\int (\frac{x}{x + 2}) d x

x \to 7 lim (\frac{x - 8}{x - 7})

y^{^{''}} = y - 3 x
