hallo I just installed sage today and probably the problem I have at the moment is a typical beginner problem, but unfortunately the tutorial was not helpful concerning this points. I am very in favor for sage, especially because it is written in python but I think I need a somehow better (more details) tutorial. Can anybody link me to another one (I read the tutorial provided on the sage webpage)? I define a equation which I would like to integrate... I simplified the equation to reduce the possible errors
if I use rho = 0.0058/((r/2.4)*(1+(r/2.4))^2) integral(rho,r,0,100000) this does not work because for r=0 rho is not defined. But anyway I want to integrate over the complete radius. What do I have to do? I can avoid the problem by using integral(rho,r,0.000001,100000) this gives: 0.01392*(10.6953303525 - (125003*log(500012) - 125003*log(100000) - 3)/ 125003) how is it possible to force sage to give me one value and not this helpless term above? thanks regards florian --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
