Cramer's Rule Solving 3x3 Linear Equations on Casio fx-991ES Scientific Calculator + Shortcut Trick!

[@princekokuselasiagble7079]

Even though I already know how to solve a 3*3 linear equation, I can now confirm my answers using the calc. through this awesome video you made so well done and thank you, keep it up.

[@infiknight8698]

I struggled so much with this but you made it so easy. Thank you

Hello! Is there a way to compute a LS on the calculator when the determinant is 0 ? I usually solve LS on the calculator using Cramer Theorem (x= A inverse *y ) however I do not know hot to solve it on the calculator when (a) the matrix is not square (b) the determinant is 0 [I know how to do it without the calculator, but i was interested in understanding if there was a way to do it with the calculator) thank you!

[@nageshodedra5367]

Thank you very much in ET iam solving equations without calculator bcoz i don't know how to solve this in calc.when i was solving equ my own i always getting wrong answer but now with calc i will get answer right.ET is very tough at IIT first year but you make it essy

@sujoy how to solve complex number equation using crammer ? i mean the equations we get on applying mess or node analysis on AC circuits

[@abdulrabtalpur]

Great video dear thank you so much, much need one...

[@jmoncepe9627]

it is easier if you use mode 5 then press 2... no need to get the determinant and matrices to solve for x, y, and z.

[@anavkatwal3986]

you are a life saver

[@nikitarijal5922]

Can't thank you enough

[@Talal_alrowaie]

broo tomorrow is my exam a found your video in the last moment you don't know how much you help me thank you 💙💙💙💙💙

[@dumbcat5037]

exactly at 6:41 where did the matrix go?? May be there's a glitch

[@aishasiddika664]

Tq soo much u helped me lot Keep doing it And help us🤘

[@ramyamohan1685]

GOOD ONE

[@emanuelguadamuz2785]

You should explain each solving method showed at the end of the video.

[@prathameshnerkar6014]

thanks. .it is very useful...of all engineering students.. thanks alot

[@JOMHEL520]

Mr.Sujoy, why that you dont use the MODE 5:Equation, option 3?

[@sujoy70]

+Jo S To show useage of MATRIX mode. But you can use EQN to solve eqns directly.

[@AbdulKhan-kq2wv]

Awesome Work. Thanks

[@tusette9641]

Hello there, ok I gotta question for you sir. If I want to solve a similar equation but it has only X and Y =Z and there is 3 of them, how can I solve that? so it will kinda look like this, X +Y= Z X +Y= Z X +Y= Z Is there a way to solve this using fx991?

[@sujoy70]

+Moayad Kennedy Check my this vid- kzbin.info/www/bejne/a529fGaQndqLe7s If you like any of my videos,I'd request you to please like & share it. Because sharing is caring :-)

[@tusette9641]

+Sujoy Krishna Das my man Sujoy, thanks for replying but the video link didn't really helped! it didn't really answer my question! I think there is no way to solve that kind of an equation using fx 991 . thank you anyway.

[@sujoy70]

+Moayad Kennedy Plz write the question below as it is. I'll check.

[@tusette9641]

+Sujoy Krishna Das X + Y + Z =100 2000X + 6000Y + 8000Z=400000 and even the matrix -2 3 -7 9 3 -2 0 -2 Thank you for replying though

[@sujoy70]

+Moayad Kennedy In linear equations, if there are 3 variables then there's to be 3 linear equations to solve it. However in Linear Programming (Simplex Method) there can be an exception. Check my Simplex Method videos to know more- kzbin.info/www/bejne/sJKbc2B5mZ2trck

thank you so much sir ...for such a good and easy methods

[@Bigly]

Any idea how I can use this calculator to do cramers rule that consist of complex numbers in the form a+bi

[@sujoy70]

***** No you can't mix matrix mode and complex modes on this calc. To know complex mode- kzbin.info/www/bejne/hX3SqaNvrbSmb5Y and matrix mode- kzbin.info/www/bejne/aYvVc3lqmMSqhtE

[@Bigly]

Ah, I have a circuit exam soon with an AC circuit. I have 2 or 3 equations that can be solved with cramers rule however they contain complex numbers. I guess I'll have to do it manually which will take long :(

[@sujoy70]

***** You can't mix and match the modes. But you can't definitely watch my vids on these two modes of the calc to know how to use them to the fullest! :-) Matrix mode- kzbin.info/www/bejne/aYvVc3lqmMSqhtE and complex mode- kzbin.info/www/bejne/hX3SqaNvrbSmb5Y

Ap bina casio use kre simple calculation bata sakte ho

[@sujoy70]

pause the video and refer the note I've written on paper. that's the normal solution of the problem without calculator. I just used calculator to make calculation easy. you can avoid calculator and do manual calculation if you want.

this was so fucking swag thank you so much
