integral of (x-arcsin(x))/(sqrt(1-x^2))

\int \frac{x - arcsin ( x )}{1 - x ^{2}} d x

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

Solution steps

\int \frac{x - arcsin ( x )}{1 - x ^{2}} d x

Expand

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

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

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

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

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

Add a constant to the solution

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

\int \frac{( x + 2 )}{( x - 3 )} d x

\int (2^{x} + x^{2})^{2} d x

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

\int (4 - 5 x)^{- \frac{3}{2}} d x

\int \frac{2 e ^{x} - 1}{e ^{x} - 1} d x
