[@autonerecords1410]

i have for some completely unknown reason taken math on for an attempt at getting into a engineering bachelor at 62. These videos are helping me get in deeper and deeper. Thankyou ..i think? Seriously great tutorial 👍

[@ExamSolutions_Maths]

Mainly A-level. What you see at present is all I have. I intend to cover the further maths later this year.

[@almanyanyukwenihango7896]

Sir I still don't understand how matrices work and I am about to face my exam

Thank you! I'm doing machine learning and we're right at the beginning, doing linear regressions and such, and we've gotten to the point where we're using normal equations to solve for the model parameters using matrices. I hadn't touched matrices in years really so I was really fuzzy on the mechanics. I appreciate the brush-up :)

[@ExamSolutions_Maths]

Pleased to hear it has offered some help. Good to also hear about real life applications.

Hi, I was wandering how would you work out this equation:
5x+3y=36
8x+2y=38

[@madpheasant47]

Just the same way, x=3, y=7

[@ExamSolutions_Maths]

Of course - go on my website.

[@AHSK-yh5ch]

If for the values that switch would their signs switch as well. And if the signs that switch, what would happen if there is no sign to swap around

Your video helped me to understand the concept in python :)

c = np.array([[16],[-4]])
print(np.linalg.inv(A).dot(c))

[@aliciaramkaran5273]

What does IYMS stands for?

[@btgkeim039]

When changing A into inverse , weren't you supposed to change signs of the major diagonal?

for 3x3 do you have to do another method?

[@eliseratcliffe2729]

Hi, I was just wondering,when I tried this out before you explained it, it did (16, -4)*(inverse) but this obviously didn't work. Is it always the case that the inverse comes before the matrix you're multiplying? Thanks for such great videos by the way! :D

[@lamaa.3232]

Yes, inverse always comes first

[@C39SHARKDRAKE]

Thanks for your help man!

[@jayagnihotri5807]

ExamSolutions
Sir is it possible to have a simulataneous equations that cannot be solved by matrices which has no solutions, one solution, infinite solutions and where there is an unknown constant in the square matrix?
Finally can there be imaginary roots for matrix equations?

[@Playlist_Two]

Not all pairs of simultaneous linear equations have solutions:
If the equations are inconsistent,
(their graphs are parallel and thus do not cross)
or, if the equations are dependent,
(the graphs coincide and thus do not cross at a single point)
the determinant will be zero.
If the determinant is zero, there will not be a solution.
I know this answer is literally 7 years too late but someone else peeping the comments might be interested. 🤣

[@HaroonKhan-jk3fh]

What a legend

[@hgg219]

I much prefer this method for solving simultaneous equations. Will this work for all simultaneous equations? Or only for those whose inverse exists?

[@ExamSolutions_Maths]

This method works for linear equations. ie of the form ax + by = c and yes, where the inverse exists which is when the determinant does not equal zero.

[@sciencematters3282]

Nice clear videos. I have done the same for university level on my channel.
