Only praises! (But how about other coordinates?)

Excellent program! The best so far in the IPhone.
I would be great be able to work in different coordinates like cylindrical and spherical.
That would be great for physicists.

Sorry    It was thumb Up of course!

Hello,

You can use whichever variables you want (e.g. greek letters, just swipe the keyboard to the right), and polar plotting is also available. You just have to e.g. write down the Laplace operator in spherical coordinates yourself (e.g. 1/r*diff(r*diff(f,r),r)+1/r^2*diff(diff(f,phi),phi)

I have added support for other coordinates to the wishlist, though.

Cheers
