integral of (e^{2x})/(sqrt(16-9e^{4x))}

\int \frac{e ^{2 x}}{16 - 9 e ^{4 x}} d x

\frac{1}{6} arcsin (\frac{3}{4} e^{2 x}) + C

Solution steps

\int \frac{e ^{2 x}}{16 - 9 e ^{4 x}} d x

Apply u-substitution

= \int \frac{e ^{u}}{2 16 - 9 e ^{2 u}} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{e ^{u}}{16 - 9 e ^{2 u}} d u

Apply u-substitution

= \frac{1}{2} \cdot \int \frac{1}{16 - 9 v ^{2}} d v

Apply Trigonometric Substitution

= \frac{1}{2} \cdot \int \frac{1}{3} d w

Take the constant out:

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

= \frac{1}{2} \cdot \frac{1}{3} \cdot \int 1 d w

Integral of a constant:

\int a d x = a x

= \frac{1}{2} \cdot \frac{1}{3} \cdot 1 \cdot w

Substitute back

= \frac{1}{2} \cdot \frac{1}{3} \cdot 1 \cdot arcsin (\frac{3}{4} e^{2 x})

Simplify

\frac{1}{2} \cdot \frac{1}{3} \cdot 1 \cdot arcsin (\frac{3}{4} e^{2 x}) : \frac{1}{6} arcsin (\frac{3}{4} e^{2 x})

= \frac{1}{6} arcsin (\frac{3}{4} e^{2 x})

Add a constant to the solution

= \frac{1}{6} arcsin (\frac{3}{4} e^{2 x}) + C

\frac{d}{d x} (x - 16)

\frac{d}{d t} (5 t)

\int cot (x) d x

n = 0 \sum \infty \frac{( - 4 ) ^{3 n}}{5 ^{n - 1}}

\int [\frac{1}{( 4 + x ^{2} )}] d x
