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

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

- 2 arcsin (x) + C

Solution steps

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

Use the common integral:

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

= - 2 arcsin (x)

Add a constant to the solution

= - 2 arcsin (x) + C

\int \frac{1}{tan ( t )} d t

\int \frac{x}{( 2 x ^{2} + 50 ) ^{2}} d x

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

\int (x - 2) d x
