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 ...

For inexact solutions, read up on linear such optimizations....
With linear systems, python has bindings to linear algebra and matrix (and the docs always confuse me more than they help, too).
Nonlinear) equations simultaneously.

I'm trying to figure out how to use Mathematica to solve systems of equations where some of the variables and coefficients are vectors. A simple example would be something like
where I know A , V , and the magnitude of P , and I have to solve for t and...

The title says it all basically, I'm looking for books and resource to teach myself linear algebra to be used in 3D graphics programming. I prefer practical approaches to teaching over theoretical (even though math is what, 99.99% theory?) ones, so the...

Does anyone out there understand stupid geometry?? Im stuggling to make it through the class. I dont understand it and was told I cant ride til grade comes up...apparently school comes first:P
What is the point of it anyway???

Before taking Differential Equations/Linear Algebra in my first year of college, I am brushing up on Algebra I/II, Pre-Calculus, and Calculus I/II. Should I also run through Trigonometry as well or should I not waste my time on it if I don't have enough...

Geometry is not needed, so don't waste your time with that.
Refreshing trig is a good idea, but you and derivatives in which trigonometric functions appear .

It seems that many projects slowly come upon a need to do matrix math, and fall into the trap of first building some vector classes and slowly adding in functionality until they get caught building a half-assed custom linear algebra library, and depending...

Eigen -
Benefits: Clean....
I'll add vote for Eigen: I ported a lot of code (3D geometry, linear decomposition and solving, etc, since these are outside the realm of traditional graphics/geometry applications.
But an interesting read.

I'm doing a chassis design project for my major project in my degree (2nd year). The design uses pushrod suspension.
As well as creating a 3d cad model (Autodesk Inventor Prof 2012) of my chassis design I am looking to create a simulation of the suspension...

Hi folks,
I have a basic question I would like to ask.
I ll start from the Euclidean analogue to try to explain what I want.
Suppose we have a smooth function (real valued scalar field)
[itex]F(x,y)=x^2+y^2[/itex], with [itex]x,y \in ℝ[/itex].
We also...

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 ...

(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.
