integral of 2/(sqrt(5-5x^2))

\int \frac{2}{5 - 5 x ^{2}} d x

2 (\frac{x}{5 - 5 x ^{2}} - \frac{1}{5} (- arcsin (x) + \frac{x}{1 - x ^{2}})) + C

Solution steps

\int \frac{2}{5 - 5 x ^{2}} d x

Take the constant out:

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

= 2 \cdot \int \frac{1}{5 - 5 x ^{2}} d x

Apply Integration By Parts

: \frac{x}{5 - 5 x ^{2}} - \int \frac{5 x ^{2}}{( 5 - 5 x ^{2} ) ^{\frac{3}{2}}} d x

= 2 (\frac{x}{5 - 5 x ^{2}} - \int \frac{5 x ^{2}}{( 5 - 5 x ^{2} ) ^{\frac{3}{2}}} d x)

\int \frac{5 x ^{2}}{( 5 - 5 x ^{2} ) ^{\frac{3}{2}}} d x = \frac{1}{5} (- arcsin (x) + \frac{x}{1 - x ^{2}})

= 2 (\frac{x}{5 - 5 x ^{2}} - \frac{1}{5} (- arcsin (x) + \frac{x}{1 - x ^{2}}))

Add a constant to the solution

= 2 (\frac{x}{5 - 5 x ^{2}} - \frac{1}{5} (- arcsin (x) + \frac{x}{1 - x ^{2}})) + C

\int \frac{2 x - 3}{3 + 4 x - 4 x ^{2}} d x

\int \frac{( 1 + e ^{x} )}{( 1 - e ^{x} )} d x

\int \frac{cos ( u )}{sin ( u ) + sin ^{3} ( u )} d u

\int e^{\frac{- x ^{2}}{5}} d x

\int 12 t e^{t} d t
