Hello, thanks for reading.
I'm working on single variable calculus here: Basically what I need is what "find_root" does, but I need a list of ALL roots in a given interval, not just one.
So I've been playing with "solve". I found this piece of code which works in most cases:
sage: roots = solve(f(x),x,solution_dict=True)
sage: roots = [s[x] for s in roots]
sage: num_roots = map(n, roots)
but it gives an error if the function is periodic and has inifinite roots, becuase the symbolic expression that "solve" gets has infinite solutions too.
Defining a desired interval should solve this issue, but I have no idea how to implement such thing!
Thanks you and have a good day.
