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

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

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

Solution steps

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

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

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

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

\int 1 d x = x

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

Add a constant to the solution

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

\int \frac{( 6 x - 6 )}{x ^{2} - 2 x + 5} d x

\int \frac{x I n ^{5} ( x ^{2} + 3 )}{x ^{2} + 3} d x

\int \frac{9 x ^{2} - 2 x}{1 - x ^{2} + 3 x ^{3}} d x

\int (10 x + 2) d x

\int cos (\frac{2 x}{5}) d x
