integral of 5xsqrt(1-x^2)

\int 5 x 1 - x^{2} d x

- \frac{5}{3} (1 - x^{2})^{\frac{3}{2}} + C

Solution steps

\int 5 x 1 - x^{2} d x

Take the constant out:

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

= 5 \cdot \int x 1 - x^{2} d x

Apply u-substitution

: \int - u^{2} d u

= 5 \cdot \int - u^{2} d u

Take the constant out:

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

= 5 (- \int u^{2} d u)

Apply the Power Rule

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

= 5 (- \frac{u ^{3}}{3})

Substitute back

u = 1 - x^{2}

= 5 (- \frac{( 1 - x ^{2} ) ^{3}}{3})

Simplify

5 (- \frac{( 1 - x ^{2} ) ^{3}}{3}) : - \frac{5}{3} (1 - x^{2})^{\frac{3}{2}}

= - \frac{5}{3} (1 - x^{2})^{\frac{3}{2}}

Add a constant to the solution

= - \frac{5}{3} (1 - x^{2})^{\frac{3}{2}} + C

\frac{d}{d x} (\frac{3 x + 2}{x + 1})

\int_{0}^{1} 8^{x} d x

\int \frac{1}{1 - 3 x ^{2}} d x

\frac{\partial}{\partial z} (5 e^{x} cos (yz))

- \frac{9}{x ^{2}}
