It seems like this should happen automatically too: In [45]: 1/(-sqrt(2)/2 - sqrt(2)/2*I) Out[45]: 1 ───────────────── ⎽⎽⎽ ⎽⎽⎽ ╲╱ 2 ⅈ⋅╲╱ 2 - ───── - ─────── 2 2 In [47]: (1/(-sqrt(2)/2 - sqrt(2)/2*I)).expand(complex=True) Out[47]: ⎽⎽⎽ ⎽⎽⎽ ╲╱ 2 ⅈ⋅╲╱ 2 - ───── + ─────── 2 2 -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
