Derivatives for trig functions

I am a college student new to Matlab. How do I find the derivative of y with respect to x:

y=sec^-1*(3x^2+1), x>0

Start with the Symbolic Math Toolbox:

syms x positive real
y(x) = asec(3*x^2+1);

then use the appropriate function to calculate the symbolic derivative.

If ‘x’ is a vector, use the gradient function to calculate the numeric derivative, and remember to use element-wise exponentiation in the asec argument.

I leave the details to you.
