Functions with operation (multiplication) as argument
Suppose I have functions f, g1, g2, h and an operation ∗, which is not necessarily multiplication, satisfying the following relations:
f(X∗Y)=g1(X)g2(Y)+g1(Y)g2(X)+f(X)∗f(Y)+h(X∗Y)
h(X∗Y)=h2(X)∗g1(Y)
How to find a symbolic expression for f(X7)?
I don't understand your question;
f(X*Y) = ...
does not seem to be valid Python syntax. Could you provide the full code of what you are trying to do?
