One way to get around this is to define the real and imaginary parts of the function and find roots of the sum of their squares: sage: x = var('x') sage: f = 1 - exp(I*x) sage: fr = real_part(f) sage:...

There are a couple of ways to get around this: sage: find_root(lambda x: RR(abs(1-exp(I*x))),-1,1) 5.5511151231257827e-17 sage: find_root(simplify(abs(1-exp(I*x))),-1,1) 5.5511151231257827e-17 Under...
