[sage-support] legend_label doesn't work with graphics_array

2011-12-10 Thread v_2e
Hello! Today I have noticed that if I cannot use the legend_label plot parameter while joining several plots in one grahpics_array object. For example, the following code works fine: plot1 = plot(sin, xmin=0, xmax=8*pi) plot2 = plot(cos, xmin=0, xmax=8*pi) total_plot

Hi, I'm having trouble evaluating this integral integral( x / (exp(x) - 1) , (x,0,oo)).n() I get TypeError: cannot evaluate symbolic expression numerically The answer (according to mathematica) should be pi^2 / 6 Is something wrong with my code? Thanks! -- To post to this group, send email
