$$\frac{y}{\sqrt{5 - y^{2}}}$$

y/sqrt(5 - y^2)

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d y} \frac{f{\left(y \right)}}{g{\left(y \right)}} = \frac{- f{\left(y \right)} \frac{d}{d y} g{\left(y \right)} + g{\left(y \right)} \frac{d}{d y} f{\left(y \right)}}{g^{2}{\left(y \right)}}$

$f{\left(y \right)} = y$ and $g{\left(y \right)} = \sqrt{5 - y^{2}}$ .

To find $\frac{d}{d y} f{\left(y \right)}$ :
1. Apply the power rule: $y$ goes to $1$
To find $\frac{d}{d y} g{\left(y \right)}$ :
1. Let $u = 5 - y^{2}$ .
2. Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d y} \left(5 - y^{2}\right)$ :
  1. Differentiate $5 - y^{2}$ term by term:
    1. The derivative of the constant $5$ is zero.
    2. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $y^{2}$ goes to $2 y$
      So, the result is: $- 2 y$
    The result is: $- 2 y$
  The result of the chain rule is:
  
  $- \frac{y}{\sqrt{5 - y^{2}}}$
Now plug in to the quotient rule:

$\frac{\frac{y^{2}}{\sqrt{5 - y^{2}}} + \sqrt{5 - y^{2}}}{5 - y^{2}}$
Now simplify:

$\frac{5}{\left(5 - y^{2}\right)^{\frac{3}{2}}}$

The answer is:

$\frac{5}{\left(5 - y^{2}\right)^{\frac{3}{2}}}$
