integral of 1/(sqrt(e^{2x)-4)}

\int \frac{1}{e ^{2 x} - 4} d x

\frac{1}{2} arctan (\frac{e ^{2 x} - 4}{2}) + C

Solution steps

\int \frac{1}{e ^{2 x} - 4} d x

Apply u-substitution

: \int \frac{1}{u ^{2} + 4} d u

= \int \frac{1}{u ^{2} + 4} d u

Apply Integral Substitution

= \int \frac{1}{2 ( v ^{2} + 1 )} d v

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}{v ^{2} + 1} d v

Use the common integral:

\int \frac{1}{v ^{2} + 1} d v = arctan (v)

= \frac{1}{2} arctan (v)

Substitute back

= \frac{1}{2} arctan (\frac{e ^{2 x} - 4}{2})

Add a constant to the solution

= \frac{1}{2} arctan (\frac{e ^{2 x} - 4}{2}) + C

\int x^{2} ln (4 x) d x

x \to - \frac{π}{4} lim (sec (x))

x \to 1 lim (+ (\frac{1}{x ^{2} - 1}))

\int 3 x d x

\int sin^{2} (2 x) cos^{2} (x) d x
