Dear Math Group:-
Suppose we have:-
x = a * e + (2*b - 3*a^2) * e^2
Now let us find such functions:
F(x) = 1 + a * e + (2 * b - a^2) * e^2 + ......
we are just interested in the first three terms.
Now two such functions can be:
F1(x) = 1 + x + 2 * x^2
F2(x) = (1-x)/(1-2*x)
How can we find all such functions F(x)?
