Hi,
I have something like
x/Sqrt[a^2+b^2]+Sqrt[a^2+b^2]/y
and I'd like to substitute Sqrt[a^2+b^2] by r.
x/Sqrt[a^2+b^2]+Sqrt[a^2+b^2]/y //. Sqrt[a^2+b^2]->r
gives:
x r
------------- + -
Sqrt[a^2+b^2] y
(replace one only in the numerator)
How to replace Sqrt[a^2+b^2] by r everywhere in the expression?
Thanks.
S.
