Checking for Equality and for Equivalence of Symbolic Expressions

[GpuCoder]

I’m having trouble even checking for syntactic equivalence

julia> using Symbolics

julia> @variables t
1-element Vector{Num}:
 t

julia> (t^2 - t^3) == (t^2 - t^3)
(t^2 - (t^3)) == (t^2 - (t^3))

julia> (t^2 - t^3) === (t^2 - t^3)
false

I’d like a comparison that recognizes that

-t^3 + t^2 == t^2 - t^3

That is, algebraic equivalence, not just syntactic equivalence.

@GpuCoder

-t^3 + t^2 == t^2 - t^3

Does this work?

julia> isequal(-t^3 + t^2, t^2 - t^3)
true
