Maple

How can find maximum and minimum values of function f(x,y) and location?

f(x,y):=cos(x*y)*(x^2+y^2)^0.5   from x=0..1,y=0..1

f := proc (y) options operator, arrow; -(1-tanh(y-.25)^2)^2+2*tanh(y-.25)^2*(1-tanh(y-.25)^2) end proc;
g := proc (y) options operator, arrow; (2*cosh(y-.25)^2-3)/cosh(y-.25)^4 end proc;

f(10);
-8
2.719999946 10
g(10);
-8
2.718614181 10

g(y) is simplify (f(y)), but f(10) is not equal g(10), why?
