I have noticed unexpected behavior when trying to take the absolute
value of a complex exponential (e^{i\theta}). For example, the following
command fails with "unable to simplify to float approximation":plot(abs(exp(i*pi*x)),x,0,3) However, the following gives the correct plot (of constant value 1): plot(abs(exp(i*float(pi)*x)),x,0,3) Why does pi need to be a float in order for abs to evaluate it and plot? Run outside of the plot function, the abs seems to do the right thing: abs(exp(i*pi*0)) and abs(exp(i*pi*3)) both return 1. I found a related bug ticket (#6926), but I still see this behavior despite those bugs being marked fixed. The difference here is the "pi" in the exp(). I am running Sage Version 4.5.2 on Mac OS 10.6.4. Please let me know if I'm doing something wrong or if this should be filed as a bug.
