sqrt(3 - 4*y)/cos(5)
Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Let .

    2. Apply the power rule: goes to

    3. Then, apply the chain rule. Multiply by :

      1. Differentiate term by term:

        1. The derivative of the constant 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: goes to

          So, the result is:

        The result is:

      The result of the chain rule is:

    So, the result is:

The first derivative [src]
       -2         
------------------
  _________       
\/ 3 - 4*y *cos(5)
$$- \frac{2}{\sqrt{3 - 4 y} \cos{\left(5 \right)}}$$
The second derivative [src]
        -4         
-------------------
         3/2       
(3 - 4*y)   *cos(5)
$$- \frac{4}{\left(3 - 4 y\right)^{\frac{3}{2}} \cos{\left(5 \right)}}$$
The third derivative [src]
