Folks,
I am trying to write a program to evaluate the sum of two continued
fractions, written in polynomials of T.
I would like a short routine to evaluate 1/(1/a + 1/b + 1/r), just
working with a, b, and r if they are not equal to zero.
So, if a = 0, then evaluate 1/(1/b + 1/r)
If a, b, = 0, then evaluate 1/r
If all of a, b, r = 0, give me 0 as output.
If (1/a + 1/b + 1/r) = 0, give me 0 as output.
Assume that a, b, r are arbitrary polynomials in T.
Can someone help?
Thanks,
Diana
