2016-05-10 15:50:19 +0200 | asked a question | the plot is not drawn y=var('y') P1=plot_slope_field(sin(y)x^2,(x,-10,10),(y,-10,10), headlength=4, headaxislength=2) P2=implicit_plot(-1/2log(cos(y) + 1) + 1/2log(cos(y) - 1) == 1/3x^3,(x,-10,10),(y,-10,10)) P=P1+P2 show(P) P2 is not drawn T.T Why??? |
