[sage-support] problem with integral (Maxima)

2010-11-08 Thread pong
I have encountered a problem in using integral integral(x * sqrt((-2*cos(x))^2 + (2*sin(x))^2), x, 0, pi) correctly gives pi^2 but integral(sin(x) * sqrt((-2*cos(x))^2 + (2*sin(x))^2), x, 0, pi) results in a complaint that Maxima encountered a Lisp error: 2 is not of the type LIST. Why so?

I'm trying to build a power series, and when I call the function to build it, sage responds Display all possiblities? (y or n). I hit n, then the same command pops up and then computes the power series correctly. Is there some way to get it so I don't have to hit n (i.e. avoid the Display

Sounds like you have a tab in there somewhere, it typically shouldn't be doing this. On Mon, Nov 8, 2010 at 7:27 AM, JJBWebb johnjackw...@gmail.com wrote: I'm trying to build a power series, and when I call the function to build it, sage responds Display all possiblities? (y or n). I hit

I want to write code that does the following Given ideals I,J in CC[x1,...,xn] check if Radical(I+J)=Radical(I)+Radical(J) also maybe throw in an example of yes and no just to see it working Radical(I)={f:there is an m such that f^m is in I} (f is a polynomial of CC[x1,...,xn] also

I just tested the following: plot(arrow((-0.03,-0.03),(6,6))) which corrects the problem and makes it seem as if the arrow actually starts from (0,0). Is this intended? On 8 Nov., 23:46, Karsten karste...@gmail.com wrote: Thanks! This corrects plotting the sine and cosine functions. But there
