Program to solve system of equations

AI Thread Summary
For solving a system of six equations with six variables, a TI-83 calculator is recommended for linear equations. If the equations are non-linear, Computer Algebra Software like Sage can be utilized, though free options are limited. Excel is also a viable alternative for smaller problems, using matrix functions such as MMULT and MINVERSE. Users appreciate the simplicity of these tools for their needs. Overall, while options exist, the choice depends on the nature of the equations involved.

I need a easy-to-use (i.e. no programming, if possible) program that's free that can solve a system of equations with 6 variables and 6 equations. Any suggestions?

yea a ti83
 
A TI83 calcultor will do the job if the equations are linear, but otherwise you will need to use a Computer Algebra Software, of which there is no excellent free package, although sage could do reasonably at the job you are asking about.
 
Thanks for the replies. I used a TI-83.
 
Another option for a small problem like this is Excel. You can used the matrix functions MMULT and MINVERSE.
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
