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

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

- 1 - y^{2} + C

Solution steps

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

Apply u-substitution

: \int - \frac{1}{2 u} d u

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

Apply the Power Rule

: 2 u^{\frac{1}{2}}

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

Substitute back

u = 1 - y^{2}

= - \frac{1}{2} \cdot 2 (1 - y^{2})^{\frac{1}{2}}

Simplify

- \frac{1}{2} \cdot 2 (1 - y^{2})^{\frac{1}{2}} : - 1 - y^{2}

= - 1 - y^{2}

Add a constant to the solution

= - 1 - y^{2} + C

\frac{\partial}{\partial z} (y^{2})

x \to 0 lim (ln (- 1))

\int \frac{25}{( x - 4 ) ( x ^{2} + 9 )} d x

f (x) = x + 40

n \to \infty lim (1 + \frac{1}{n})
