I know that they are both either $f(x,y)=\cos(x^{2}+y^{2})$ or $f(x,y)=e^{-(x^{2}+y^{2})}$. But I can't think of a way to tell them apart. *Comment*: They both have circular symmetry but only one has some sort of wavy behavior.SpaceManSpiffWed, 16 Jul 2014 20:48:15 -0500http://calc3.askbot.com/question/109/
