Finding the intersection of a function with its derivative

I have this code:
x=sym('x'); f=2*sin(log(x)).^2; g=diff(f); h1=ezplot(f); set(h1,'Color','red') hold on ezplot(g) grid on
Now, how I can find the value of the points where they intersect?

How about:
syms x
f=2*sin(log(x)).^2;
g=diff(f);
solve(f-g) % or solve(f==g)

I see that is not getting all the apparent points of intersection
I have tried that but I wasn't sure it was correct :)
That is the thing that I want to know :). The value of all points where those 2 curves intersect
