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

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

\frac{1}{2} x arcsin (x) + \frac{1}{2} x^{2} 1 - x^{2} + \frac{1}{3} (- x^{2} + 1)^{\frac{3}{2}} + C x + C

Solution steps

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

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

= \int (\frac{1}{2} (arcsin (x) + \frac{1}{2} sin (2 arcsin (x))) + C) d x

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

= \frac{1}{2} x arcsin (x) + \frac{1}{2} x^{2} 1 - x^{2} + \frac{1}{3} (- x^{2} + 1)^{\frac{3}{2}} + C x + C

\int \int (x + y + 1) d x d y

\int \int 2 x y d x d y

\int \int x^{2} + y^{2}

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

\int \int e^{- x} d x d x
