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

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

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

Solution steps

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

Apply u-substitution

: \int \frac{5 - u}{u ^{3}} d u

= \int \frac{5 - u}{u ^{3}} d u

Expand

\frac{5 - u}{u ^{3}} : \frac{5}{u ^{3}} - \frac{1}{u ^{2}}

= \int \frac{5}{u ^{3}} - \frac{1}{u ^{2}} d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{5}{u ^{3}} d u - \int \frac{1}{u ^{2}} d u

\int \frac{5}{u ^{3}} d u = - \frac{5}{2 u ^{2}}

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

= - \frac{5}{2 u ^{2}} - (- \frac{1}{u})

Substitute back

u = e^{x}

= - \frac{5}{2 ( e ^{x} ) ^{2}} - (- \frac{1}{e ^{x}})

Simplify

- \frac{5}{2 ( e ^{x} ) ^{2}} - (- \frac{1}{e ^{x}}) : - \frac{5}{2 e ^{2 x}} + \frac{1}{e ^{x}}

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

Add a constant to the solution

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

f (x) = x arccos (x)

\frac{\partial}{\partial x} (A (B - x^{2} - y^{2} - z^{2}))

f (x) = (5 x^{6} + 4 x^{3})^{4}

\frac{d}{d x} (x + 2 x^{2} sin (\frac{1}{x}))

y = - 2 x^{2} + 4 x - 4
