20. Python to solve for systems of linear equations

You remember from math class... if you have 2 unknowns... you need to have 2 equations. Then you did substitution, elimination etc to solve for your unknown variables. A much easier way is to use linear algebra and matrices! When we write our variables/equations in a matrix we can solve easily using a inverse of the array

Now it all makes sense! the easiest explanation i've come across. Thank you so much

Easy and helpful . Thankyou😁

Can we use this for solving equations with 4 unknowns?

Awesome, really helped me finding eigenvectors, wich is a pain doing it by hand

Hello and thank you for this great video. I just wish to ask what sign is that between import and numpy ? Is it a dot? Thanks

[@nononnomonohjghdgdshrsrhsjgd]

it must be from his IDE. there is no point or dot usually between import numpy , because this the command to import a module or lib in python.
