Try these as Google searches to see 3-D graphs of the functions. The tanh() one is the best. I also like “1/x+1/y from -20 to 20”

sin(5.5x)*cos(5*y)+x*x+1 x is from -1 to 1, y is from -1 to 1, z is from 0.1 to 2.8
Yes, the tanh one is beautiful!
FYI… in Safari enable the Develop menu and enable WebGL, if you haven’t already.
