integral of (1+2e^x)/(e^{2x)}

\int \frac{1 + 2 e ^{x}}{e ^{2 x}} d x

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

Solution steps

\int \frac{1 + 2 e ^{x}}{e ^{2 x}} d x

Expand

\frac{1 + 2 e ^{x}}{e ^{2 x}} : \frac{1}{e ^{2 x}} + \frac{2}{e ^{x}}

= \int \frac{1}{e ^{2 x}} + \frac{2}{e ^{x}} d x

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

\int \frac{1}{e ^{2 x}} d x = - \frac{1}{2} e^{- 2 x}

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

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

Add a constant to the solution

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

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

\int x^{2} (x^{3} - 2)^{\frac{1}{7}} d x

\int \frac{1}{100 - x} d x

\int e^{2 c o s (x)} cos^{2} (x) sin (x) d x

x^{7}
