integral of 3/(sqrt(1-2x))

\int \frac{3}{1 - 2 x} d x

- 3 1 - 2 x + C

Solution steps

\int \frac{3}{1 - 2 x} d x

Take the constant out:

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

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

Apply u-substitution

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

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

Take the constant out:

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

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

Apply the Power Rule

: 2 u^{\frac{1}{2}}

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

Substitute back

u = 1 - 2 x

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

Simplify

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

= - 3 1 - 2 x

Add a constant to the solution

= - 3 1 - 2 x + C

e^{x^{5}}, 0

x \to 1 lim (x^{2} - 4)

\int \frac{3 e ^{2 x}}{e ^{2 x} + 9 e ^{x} + 18} d x

x \to 0 lim ((1 - 2 x)^{\frac{1}{x}})

\int_{4}^{7} f (x) d x
