I want to define a function
g(s) such that
g(s_):=f(s) in a (arbitrarily small open) neighborhood around
g(s_):=0 in a (arbitrarily small open) neighborhood around
How do I do that? It looks like Piecewise requires actual numbers to be inputted, but I don’t have numerical values of
s2, so I don’t think I can use that.
The goal would be to get it so that
g(s1)==f(s1) g'(s1)==f'(s1) g(s2)==0 g'(s2)==0
