Numerically find all roots in an interval
Is there a function to find all the roots of a function on a given interval? I'm thinking of something like this:
sage: find_all_roots(lambda z: tan(z)+z/sqrt(9*pi^2-z^2), 0, 10) [0, 2.835952326711582867481259929, 5.64146101037285257526886564, 8.338774576412169721334841011]
Thanks!
