integral of xsqrt(10-x^2)

\int x 10 - x^{2} d x

- \frac{1}{3} (10 - x^{2})^{\frac{3}{2}} + C

Solution steps

\int x 10 - x^{2} d x

Apply u-substitution

: \int - \frac{u}{2} d u

= \int - \frac{u}{2} d u

Take the constant out:

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

= - \frac{1}{2} \cdot \int u d u

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= - \frac{1}{2} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 10 - x^{2}

= - \frac{1}{2} \cdot \frac{2}{3} (10 - x^{2})^{\frac{3}{2}}

Simplify

- \frac{1}{2} \cdot \frac{2}{3} (10 - x^{2})^{\frac{3}{2}} : - \frac{1}{3} (10 - x^{2})^{\frac{3}{2}}

= - \frac{1}{3} (10 - x^{2})^{\frac{3}{2}}

Add a constant to the solution

= - \frac{1}{3} (10 - x^{2})^{\frac{3}{2}} + C

\frac{d}{d x} (\frac{1}{6} x e^{3 x})

\frac{\partial}{\partial x} \frac{1}{( \frac{1}{x} + \frac{1}{y} )}

\int \frac{6 x ^{3}}{16 + x ^{2}} d x

y^{^{'}} = 2 y + x^{2} + 9

\frac{d}{d x} ((x + 1)^{x^{2}})
