Wondering if anyone knows a simple solution for this kind of thing.
I have an expression in multiple independent variables that I perform a power series expansion on:
But this gives me every term up to x^2*y^2*z^2. Instead I want the maximum order of my terms to be 2 regardless of the variable, so my highest order terms would be x^2, y^2, z^2, xy, yz, zx. Any ideas?
Thanks in advance
