How do I solve the symbolic equation x^2 == 16*sin(x) symbolically? I
don't even get 0 as solution.

You could try:
sage: f(x)=x^2-sin(x)
sage: f.find_root(-1,1)
0.8767262153950626
sage: f.find_root(-1,0.5)

Hello there,
I'm pretty new to Sage, but it seems to be the program i was searching for a
quite long time. Basically I'm interested in using sage's calculation in
TexShop, but something seems to be broken in the automation if Sagetex in
TeXShop. I hope someone could help me fixing the issues i

Thanks, but as I wrote, I want a symbolic solution.
In particular, I wonder how I get the solution 0.

How do you evaluate a matrix polynomial with Sage ? The obvious way doesn't
work :
sage: P=x^2
sage: P(x=4)
16
sage: M=matrix([(1, -3, -1),(0, 1, 1),(-1, 2, 1)])
sage: P(x=M)

Hi,
I plot a blackbody curve and the filling is palegoldenrod.
I would like to get a rainbow filling for each color.
I tried fillalpha= with x y but that doesn't work is there a way of doing it ?

OK, i get it now, checking the doc gives me the following answer :
sage: M=matrix([(1, -3, -1),(0, 1, 1),(-1, 2, 1)])
sage: R. = QQ[]
sage: P=X^2
sage: P.subs(M)
[ 2 -8 -5]
[-1 3 2]
[-2 7

You found an answer, but the error message could be more informative.
Plus, since
M = matrix([[1]])
M^2
works, in principle we want thi

Perhaps a little code would be helpful here. Do you want a rainbow of
*different* curves? A picture of what you mean would be helpful.
