integral of (1-x^2)/2

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

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

Solution steps

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

Take the constant out:

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

= \frac{1}{2} \cdot \int 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

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

\int 1 d x = x

\int x^{2} d x = \frac{x ^{3}}{3}

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

Add a constant to the solution

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

csc^{2} (x) - 5

\frac{s - 4}{2 s ^{2} + s + 8}

\frac{\partial}{\partial y} (3 x^{2} + 5 y^{2})

x y^{^{'}} + y = - 2 x y^{2}, y (1) = 7

\frac{d}{d x} (lo g_{2} (x - 1) - 2)
