Solving Systems Of Equations Using Sympy And Numpy (Python)

In this video I go over two methods of solving systems of linear equations in python. One method uses the sympy library, and the other uses Numpy.

With gratitude, I thank you for making this video. You are a trailblazer. Following you is a blessing.

You've made a typo in your first system of equations.
You wrote: eq2 = Eq(3*x-1, -2)
It should be: eq2 = Eq(3*x - y, -2)

The first system yields x = -1/3 (3x = -1 => x = -1/3) and thus y = 11/3
The second system yields x = 2 and y = 8.

Hope that helps!

0:00 "What's going on, smart people!" - There. That's where you lost me. 😀 Just kidding. Nice video. I didn't know about the latex trick. Thank you for sharing.

Really helpful. BTW, I like your hair style~!!LOL

This is an excellent video. It helped me a ton!!! Thank you.

Andrew you just made my day . I was on rank 7 in code chef contest and used this method to solve the equation of degree 4 and got the 4th rank. Love you bro ❤

Thanks so much! This has been a great help!
My uni also uses python for physics programming so thanks again and do more python videos, please :)

Nice video. Since this video is over a year old, you may have figured this out by now. Using control-Enter is the same as having to move your mouse to click on run.Use that for about 10 minutes and it will become instinct. The little bit of time saved can add up over a long coding session.

You look like Ryan Reynolds. Very informative vid.

Great tutorial! Your channel is easily becoming my favorite! :D

Have you tried the "Successive Over-Relaxation" method? It's an iterative method with a convergence parameter, it solves large matrices MUCH faster than Gauss-Jordan does. When you get to doing Finite Difference Methods with grids in the millions, that performance matters!

Woah, I didn't know you used to make these videos too. Awesome make more, Thanks.

Great video!! I definitely enjoyed it and learned a couple of things!!

[monzz]

What are the main advantages and disadvantages of using either sympy or numpy?
Great video btw!

[abdelrhmandameen]

Great stuff, i''m just wondering why you didnt use numpy.array when solving the equ with numby?

[oldelkhot]

Thanks for the video. I was looking for an easy way to find the initial guess for a poly nomial in order to solve the equation by fsolve from scipy.optimize and importing numpy!

Hey can you integrate (3x^2 + 1) using this library to get output as x^3 + x?
If so, can you explain the procedure for this? Needed help for this asap

[kamehamehaDdragon]

I did a Java program that solves matrices using Gauss-Jordan, can't wait to learn python, muh friendlier language for math.

[aminoffline]

thx for video
i need to solve problem it look easy but it isn't
i wanna use sympy or numpy honestly it dosn't matter any thing that solves it
my equation has one variable but one is one side and the other is on other side and it wont come to other side easily cause it buried under 4 or 5 heavy Denominator
so is there a way i can solve this ?

if u know how plz help me



ps: i will bookmark this page to look for your answers

Dear Andrew Dotson,

Thank you for your video. Most helpful.

I was wondering if, perhaps, you could post some tips/techniques for evaluating the stability of ODE using Python.

Recently, there has been great development in that field using Python. One example is the LMFIT Python's library, which is most straitfoward for modelling linear and non-linear syatems. Nevertheless, we still lack a proper method for evaluating stability in an ODE system.
