integral of (3e^a)/(sqrt(4-e^{2a))}

\int \frac{3 e ^{a}}{4 - e ^{2 a}} d a

3 arcsin (\frac{1}{2} e^{a}) + C

Solution steps

\int \frac{3 e ^{a}}{4 - e ^{2 a}} d a

Take the constant out:

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

= 3 \cdot \int \frac{e ^{a}}{4 - e ^{2 a}} d a

Apply u-substitution

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

= 3 \cdot \int \frac{1}{4 - u ^{2}} d u

Apply Trigonometric Substitution

: \int 1 d v

= 3 \cdot \int 1 d v

Integral of a constant:

\int a d x = a x

= 3 \cdot 1 \cdot v

Substitute back

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

Simplify

= 3 arcsin (\frac{1}{2} e^{a})

Add a constant to the solution

= 3 arcsin (\frac{1}{2} e^{a}) + C

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

\int \frac{x ^{3}}{6 + x ^{2}} d x

\int 12 (e^{3 x} + e^{- 3 x})^{2} d x

\int \frac{x e ^{x}}{4 + e ^{x}} d x

\int \frac{3 - z}{2 + z} d z
