Short Question:
Lets say, I want to solve Project Euler problem 9 using python and some equation solving libraries.
a + b + c = 1000. a2 + b2 = c2
How do you do it.
Long Question:
I want to solve a set of equations; linear, sometimes may be quadratic ...

With linear systems, python has bindings to linear algebra and matrix (and the docs always confuse me more than they help, too).

Hello everyone,
I have a question that has been torturing me for quite some while now.
Here it goes:
Let n be a fixed integer and consider U(n), the group of n x n unitary
matrices. It is a real algebraic variety. I have also a polynomial P
in 2n^2 ...

Just not "reduce the dimension....
(In algebraic geometry) *real* algebraic geometry, in
both of which there *is* a natural notion of "measure 0" around.
It has to do with differential geometry, not with algebraic geometry.

If a PhD cannot understand the following where the geometry is
invariant, but the metric must be unique to every coordinate system to
describe this same invariant geometry.
That is reality.

The only
loophole of it, is that it makes both MATHEMATICAL and LOGICAL
sense, unlike your little equations and theories this any clearer to you.
Note the accuracy of the equations when put into practice.

In other settings (e.g., differential equations,
