[sage-support] Re: using parametric_plot for more than one function

Thank you. I just discovered that, while semantically imprecise, Piecewise() affords the versatility to do this too -- it may, in fact, implicitly do what you explained. sage: f1 = lambda x:1 sage: f2 = lambda x:1-x sage: f3 = lambda x:exp(x) sage: f4 = lambda x:s

[sage-support] using parametric_plot for more than one function

2008-05-29 Thread andrew . sundstrom
Is it possible to use parametric_plot to superimpose one function plot onto another? Currently I'm creating two separate plots, as below, but would rather see them together and at the same scale. parametric_plot( (x_1, y_1), beg_1, end_1 ).show() parametric_plot( (x_2, y_2), beg_2, end_2

I have a function that is not piecewise and cannot be symbolically integrated. Hence, I cannot use the Riemann or trapezoid approximations. Is there any other way in Sage to numerically integrate such a function? Thanks, Andrew --~--~-~--~~~---~--~~ To post to th

Greetings. I'm brand new to Sage, and am excited to get started. I've been using Maple recently, namely the 'linalg' and 'LinearAlgebra' packages. Browsing the Sage Reference Manual, I don't see an analogue for these packages. For instance, I want to perform a pseudo-inverse operation to solve
