integral of 3/(2e^{2x)}

integral

\frac{3}{2 e ^{2 x}}

- \frac{3}{4} e^{- 2 x} + C

Solution steps

\int \frac{3}{2 e ^{2 x}} d x

Take the constant out:

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

= \frac{3}{2} \cdot \int \frac{1}{e ^{2 x}} d x

Apply exponent rule:

\frac{1}{a ^{b}} = a^{- b}

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

= \frac{3}{2} \cdot \int e^{- 2 x} d x

Apply u-substitution

: \int - \frac{1}{2} e^{u} d u

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

Take the constant out:

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

= \frac{3}{2} (- \frac{1}{2} \cdot \int e^{u} d u)

Use the common integral:

\int e^{u} d u = e^{u}

= \frac{3}{2} (- \frac{1}{2} e^{u})

Substitute back

u = - 2 x

= \frac{3}{2} (- \frac{1}{2} e^{- 2 x})

Simplify

\frac{3}{2} (- \frac{1}{2} e^{- 2 x}) : - \frac{3}{4} e^{- 2 x}

= - \frac{3}{4} e^{- 2 x}

Add a constant to the solution

= - \frac{3}{4} e^{- 2 x} + C

\frac{1}{x + 2}

y^{\frac{6}{7}}

sec^{2} (x) tan (x)

\frac{300}{( 2 x + 1 )} + 12 x^{3} - 8 x

sin^{5} (\frac{x}{3}) cos (\frac{x}{3})
