(I should point out that I am new to Maple as well).

My function is h_c=[1/(2π*(√2)*a*f²)]*ln(h_c/4), and f=(a0-a)/a0

I have managed to get so far- Maple has accepted the function as an equation, and I want to plot h_c as a function of f, which, as you can see, varies according to a. I've tried...
