Evaluation of 1/(1/a + 1/b + 1/r)

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
