I've been looking for a math app that functions similarly to Grapher on Apple (or Nuclac on windows) for a few months now but havent found anything suitable. The closest ive gotten is Kayali (it doesnt have 3D support), Euler (too hard to use) and another program that wouldnt let me enter relations, only functions (ie only let me enter f(x,y)= ... not z^2+x=y-2)

Thanks in advance
