Well, it's the beginning of the year and I'm already stumped :-X.
The problem tells me to add, subtract, multiply and divide two given functions, but I am not sure how to continue since they are square roots.
Here are the functions:
f(x) = sq.root(1+x) and g(x) = sq.root(1-x)
Find: f+g, f-g, fg, and f/g
Any help is much appreciated.
