[sage-edu] Solving contour integrals in SAGE

2008-05-12 Thread ohitmano
Hi all, need do solve contour integral of a very complex function contour is provided with equations: x = cos(q) + cos(4q); y = sin(q) - sin(4q). function is very long and complex and I won't post it here, but will say about some conditions: it depends on variable(r) that must be >0 because it con

I think this question is better posed on sage-support, which I am cc'ing. sage-edu is about teaching with SAGE. Am I correct in assuming you have a parameterization of your line integral (with parameter q) and so you can write the contour integral as int_a^b f(q) dq after some substitutions? I'

I don't agree with Ted's implication that to serve the precollege community well a CAS' graphical environment needs to be "specifically designed" to met their needs. For example Mathematica's GUI supports both simple computations and sophisticated ones without having two different notebook interf
