Question: Implicit plot with trig and hyperbolic terms

Trying to plot cosxcoshy = 1, I am obtaining close to what i expect to see, but the graph should pass through the origin and maple is plotting it with no defined values for -0.2 < x < 0.2. The line is also not very smooth. This is what i have entered

 implicitplot(cos(x)*cosh(y) = 1, x = -3 .. 3, y = -5 .. 5)

any help would be greatly appreciated
