@bikeous23 i am not sure how to respond. you just seem a bit angry about it all. this is a wonderful way to solve large systems of equations. what method do you have that is more efficient?
and what does: there is huge room for error? there is no room for error if one can do arithmetic correctly. yes, there are lots of computations, but we are not adding 2 + 2 here...
and no, math is not as trivial as you seem to make it.

@SpaceBandit666 if i wrote out every single arithmetic step, this video would take about 10 years to make. you need to be able to fill in some stuff as you go. there is a pause button. try to fill in the steps yourself and you will actually start learning.

how do you do homogenous linear equations?
-
Good day! Is it necessary to change the rows? At our school, we weren't introduced to that technique.
-
You're in pre calc... What kinds of systems are you solving? 2, 3, MAYBE 4 equations? Try using substitution and elimination on a big ol' 6x7 system without Gaussian elimination and tell me your way is faster and with less margin for error.

Ugh is it just me or is Calculus actually more fun than LA? Getting the hang of it though thanks Patrick!

tnx.. i learn a lot more power man..

@elleen54 you have to make it a one or else the end results are correct

After using your video's for so long Patrick i now watch these immediately after the lectures instead of waiting for the night before the exam. I have to say it has made this semester a lot more smooth than usual!
Thank you!!!!!!

Thanks for the video. I couldnt figure out how to solve using this method but after watching your video I figured it out. just in time for my final exam tomorrow. Thanks!
