Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Apply the quotient rule, which is:

      and .

      To find :

      1. Apply the power rule: goes to

      To find :

      1. Apply the power rule: goes to

      Now plug in to the quotient rule:

    So, the result is:


The answer is:

The first derivative [src]
arcsec2
-------
    ___
2*\/ x 
$$\frac{arcsec_{2}}{2 \sqrt{x}}$$
The second derivative [src]
-arcsec2 
---------
     3/2 
  4*x    
$$- \frac{arcsec_{2}}{4 x^{\frac{3}{2}}}$$
The third derivative [src]
3*arcsec2
---------
     5/2 
  8*x    
$$\frac{3 arcsec_{2}}{8 x^{\frac{5}{2}}}$$
