Find the second derivative of f(x)=sec(x).

Step-by-step explanation:

The given function :

First we find the first derivative of the function, so differentiate both sides , with respect to x, we get

Now, to find the second derivative, we differentiate again it with respect to x, we get

Hence, the  second derivative of is

for b its (t) and c its (d)
