| 2012-02-26 04:09:02 +0200 | asked a question | complex numbers and parametric curves I would like to be able to plot a 2d parametric plot of zeta(t+I), -2 <= t <= 2, where I is the square root of -1. But complex numbers and parametric plots seem to barf at each other. I tried many variants of the following code: parametric_plot( (zeta(t+I).real(), zeta(t +I).imag()), (t, -2, 2)) But I get the following kind of response: TypeError: Unable to convert 1.00000000000000*I to float; use abs() or real_part() as desired |
