Simultaneous Equations Matrix Method : ExamSolutions

[@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

[@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 👍

[@shellymcdougall4320]

Your explanations are so much more understandable than my teacher's explanation. Thanks a lot for all your help! ;)

[@ExamSolutions_Maths]

I am pleased to hear it helped.

you are a living legend

[@ozzyfromspace]

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.

[@ExamSolutions_Maths]

Well done and good luck at uni.

[@malopemdluli5653]

I had difficulties understanding this, but you made it seem easier. I just want to thank you for giving your best for us students to do better. You are much appreciated.

[@ExamSolutions_Maths]

You're very welcome!

Thank you for the explanation, your videos about matrices will be very useful on my linear algebra exam

[@vitumbikowyclifngoma9509]

Wow.... So easy to understand..I've really grasped the idea easily. Am thankful

Great stuff mate thank you, it would be nice if you went a tiny bit slower but it is still better than 99% of the videos out there. Keep it up! :)

[@baldeagle6113]

Thanks a lot mate you really helped me

[@UrayayiMwawonazawa]

I don't know why but I chose to take Additional maths when l am already terrible in normal math but this might have helped me 😅😢🎉😂❤.

[@wattkris968]

Thank u. I have a text in just a few hours and you made it easier than how my teacher teaches it

Thanks dear teacher

[@EnduranceObot-m4m]

You are amazing Sir

[@amitkshankar]

Thank you - Brilliant
Your video helped me to understand the concept in python :)
import numpy as np
A = np.array([[5,-2],[7,6]])
c = np.array([[16],[-4]])
print(np.linalg.inv(A).dot(c))

[@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

[@I3havs]

This was the particular topic,I missed in my class due absenteeism
And In exam use to solve the equation normally instead of using matrix method, and each time my marks was deducted.
Then before my first preboard,I have finally watched this savage one😅😅😅

[@ayshamanal1736]

thank you! was a great help :)

[@ExamSolutions_Maths]

That's good to hear, thanks.

[@mybishthing]

can you please do one for matrices with no solutions, one solution, infinite solutions when there is an unknown constant in the square matrix!

The answer is supposed to be 3, 4
Idk how I got mine…….

[@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

[@abenathistuurman4598]

[@YashVerma_twistedsoul]

So what if our equation was a singular matrix, we couldn't find the values of x and y then?
