Problem with supercripts
I've read that variables can be subscripted with underscore "_" and superscripted with caret "^". However supescripting doesn't seem to work. I think the caret is seen as a power operator. How to work around this?
Subscript example that works:
var('x,y,z_a') eqn = x == y*z_a solve(eqn, z_a)
Superscript example that fails:
var('x,y,z^a') eqn = x == y*z^a solve(eqn, z^a)
