I already have the bivariate decomposition worked out (version 0.1). The reason I'm interested in the bivariate is because that is the only case (presently) that I know solve can deal with.
``` bivariate_type(f, x, y, **kwargs) Given an expression, f, 3 tests will be done to see what type of composite bivariate it might be, options for u(x, y) are:: x*y x+y x*y+x x*y+y ``` e.g. if P(x) returns a polynomial then we can solve P(cos(x) - sin(x)), P(x*exp(x) - 3), etc... -- You received this message because you are subscribed to the Google Groups "sympy" group.
