Hi,
i am looking for a way to solve this equation 10* (2* x^2 + y^2 + z^2
- 1)^3- x^2*z^3 - 10*y^2* z^3=0 to z but I did not find a way to do
it in sage. So if anybody knows how to do it please answer me- Thanks.

This is embarrasing but in the interest of technical honesty I have to
confess that I created a book mark in Firefox for Sage. I don't know
how but the IP in the book mark was wrong. That fixed it.
Works great now.

Unless 24.9... = -24.9..., there seems to be a bug:
sage: f = sqrt(25-x)*sqrt(1+1/(4*(25-x)))
sage: f.integral(x,9,16)
integrate(sqrt(1/(4*(25 - x)) + 1)*sqrt(25 - x), x, 9, 16)
sage: f.nintegral(x,9,16)

In this special case, if you let A = ((x^2 + 10*y^2)/10^(1/3) (assuming I did
the algebra right, note there are 3 such A's, but only 1 real one) then you get
sage: A = var(A); solve(2* x^2 + y^2 + z^2 - 1- A*z==0,z)
[z == (A - sqrt(A^2 - 4*y^2 - 8*x^2 + 4))/2, z == (sqrt(A^2 - 4*y^2 -
8*x^2 +
Hi all,

Hi Michael,
Thanks for the discussion link. I'll play around a little with the
patch and see if I can do anything with config.guess.
Looks like a pretty tricky build! If I come up with anything useful
I'll be sure to let you know.
Take care
