SageMath Tutorial - Solving A Linear System of Equations

nafion (37)in #utopian-io • 8 years ago (edited)

Hi everyone, today I would like to make my first contribution to Utopian by presenting a video tutorial on the open-source math program: SageMath! SageMath is an alternative to paid software such as MATLAB and Wolfram Mathematica.

This video will show how to solve a linear system of equations, in it I show a system with two variables and another system with three variables.

I'm using the Windows version in this demonstration and the software can be downloaded from https://github.com/sagemath/sage-windows/releases.

Your contribution cannot be approved because it does not follow the Utopian Rules, and is considered as spam.

Explanation:

far too short
contains a video, yet doesn't qualify for a video tutorial either because your video doesn't contain any voice narration (it's silent)
you copied/pasted 3 extremely simple linear equations from another source

PS: You could have at least tried to solve a Laplace transformation? Like for example this one:

sage: de1 = maxima("2*diff(x(t),t, 2) + 6*x(t) - 2*y(t)")
sage: lde1 = de1.laplace("t","s"); lde1
2*((-%at('diff(x(t),t,1),t=0))+s^2*'laplace(x(t),t,s)-x(0)*s)-2*'laplace(y(t),t,s)+6*'laplace(x(t),t,s)

Bonus bounty: if you will explain, in a reply to this comment, what my Laplace transformation is about, then I will give you a personal comment upvote! From @scipio! Good luck!

Lack of narration: There is narration, did you have speakers turned off?
Too short: ok I guess you have a point.
Copy and paste: lol no I came up with the equations out of thin air, it's not that hard.
