2020 gate ke liye ak video banaiye. Full Math with important topic only by Trick. Bcz i like your trick.

Hello Mr. Shrenik Jain, this is my humble request to you to make videos on GATE 2020 syllabus based on some tricky rules...your videos are quite fruitful for us...

PI 2008 - The determinant of an Orthogonal matrix is 1 or -1 but the reverse may not be true. I mean if the determinant of any matrix is 1 or -1 then it is not necessary that it is an Orthogonal matrix so the last trick may lead to the wrong answer. Apart from this other tricks are good :)

Year of award to your channel in "Tech mathematics"

for the question from EC2009(13:50) use property of sum of diagonal value = sum of eigen value. AND for last question their is another simple trick i.e. A.A^-1 = I just check the first element to be 1

Trace = Sum of Eigenvalues Det = Product of Eigenvalues

For Mathematics Students.. Sometime, we don't even calculate the Det..

I swear, You are a genius!

Dear sir from eqn 2 x1=x2, put in eq 3, x3 =1, form eqn 1, 2x1 =2 . X1 =1, x2=1 x3 =1. Unique solun.

Very useful video...I loved it.... Keep making this kinda videos and encourage and support us sir..... Verryyyyyy useful and nice video..❤️❤️😍😍👍👍👍👍👍👍👍 good job

Last question can also be solved by.. (33:54) Product of A and A inverse is Identity matrix. So just take first row of given matrix and multiply it with first column of every option It should give answer 1. Btw nice video. Thanks

Mind-blowing!! this video very first my thinking process, thanks a lot bottom of heart's sir❤️❤️

Great job....for preparation of GATE.

Bahot shandar. ..tricks he...thank you sir

Vector calculas or intergal calculas k bare me kuch vedio please banaye ..🙏🏻🙏🏻🙏🏻 Short tricks process ...

1 Question me ek trick mai batata hoon 1 equation ke coefficient ko man lo a1,b1,c1 r 2 equation ke a2,b2,c2 agar a1/a2 is not equal to b1/b2 hai toh unique solution agar a1/a2=b1/b2=c1/c2 ho gaya toh infinite solution..

In the second question of eigen values ..... if more then one option satisfies the condition of algebric sum then how can we decide right solution????

@8.02 p sum of eigen values = sum of diagonal elements .............. But if two options are given with same sum then how can we find right answer

Please upload videos on probability and permutations and combinations also having tips and tricks ...it is my humble request sir

Lamda not equals 6,mue=20(b option also correct according to your explanation). Please think.

Method 2 is allowed of all matrices...? Plzz reply for eigen values.

This is very useful for gate aspirant thank you

I like method 2, thanks for this wonderfull video sir👍

Your tricks are very simple & very helpful to us sir.

Rank=1 for ques 3( EC 2006 ) as determinant for 2*2 matrix is zero by seeing minor of A23

Sir it's totally "Jhakkas, pharoo, Jabardasht ".Thanq.

Ur tricks are easy to understand&time saving tq sir for ur video

Bro u can post triks PDF link notes plzzz ...

I have a dought We have another property that is Sum of eigen value = sum of leading diagonal element From this property we get ans -1 So hw it is possible that two property intersect each other

That was really good, keep it up

If determinant is equal to 0 for 2×2 matrix then what will be the rank? Sir.!

Thanks sir You deserve millions of subscriber ❤️🥰😍😍

Awesome techniques brother , thanks a lot for the video

I started this video as timepass but it went very productive video of the day.. Nice tricks

M2is very easy nd I easily understand thank you so much 🙏

Sir in 2 question sum of diagonal is also 0 so we can't consider 0 and verified with option

Thank you sir your explanation was very effective, please upload more and more videos like this!

Nice info.. but video name should be tricks for Linear Algebra for Gate.

This tricks valid for all same types of prblms??

bro is the 2nd trick valid for 3x3 matrix also? I mean in JEE main also?

It's vry helpful video for us nd we want more tricky math video. Thanq

Sir I am civil engineering student . I'm preparing gate exam and other related engineering exam . I want your short notes .Please tell me how many cost of maths note ... Sir

Please please give expected question for upcoming AAI ATC/AO exam please.... Time is very less we need your talent

9:35 Given matrix is not an orthogonal matrix since they mentioned it was orthogonal, the answer is C but the given matrix was not an orthogonal matrix. the determinant of the given matrix is 8 which means it's not an orthogonal matrix

Tdy is friday, sunday i have gate exam, very useful time saving tricks. Thank you sir 😀

Nice..thanks for the explanation

Good method very easy to understand thanks sir 🙏🙏🙏

bro then what about the solution of the equations if the determinent is equal to 0 and lesser than 0?

wow thanku so much ...youre are amazing

From where i will get engineering maths notes????

What is the condition for other like infinity solution ,no solution and other

EC 1994 system of linear equation question Are you sure answer is unique solution???

Please upload the English version if this vedio

You r absolutely great sir ❤

Sir Unique solution trick is not working on other problems 1.5x-0.5y=2 4x+2y+3z=9 7x+y+5z=10 It has unique solution but det=\=0 athahe sir

Really helpful. Thank you.

It is very helpful to me thank u

Sir if det A is not equal to zero.. Then what's it sir ?

First question matrix me le hi jaana kyu? 😂😂🤣🤣 X1=X2 And given that X1-X2=0 Just put in 3rd gives X3 = 1 Put in first gives 2X1+1=3 Which gives X1=1 Now x1=x2=1 and X3 is also 1.🤣 Which is indeed a unique solution. 🤣

What a wonderful vedio this is😌

One of the best you are 👍

How are option a and c diferent for the last qs?

Very helpful thanks sir

Amazing brother... Thank you so much....

No solution pe bhi determinant note equal to 0 aayega... Only many solution me 0 aayega.

In rank of matrix use equal triangle technique to get rank

What about the case when det = 0, how can we differentiate between no solution and infinite solution?

Why're this questions a little simple, from thosr previous question papers I see, problems are a bit more different

Thnk u sir,plzzz 2021 ke liye video bnaiye plzz help us

in first quation if determinant equal to zero then? what the answer sir

2nd last question mai... sum of diagonal = sum of egien values vali property fail ho rhe hai...0+0=0 aayega..par egien values ka sum kiya toh 0 nhi aa rha... Plz acknowledge

Sir, If determinate is zero then which condition we r follow

sir what if determinant is zero?

Your number is not coming in what's app....?

God bless you sir

I did not understand at 24:14. How you eq-3 is equal to 77?

13:38 ...what if we take 1111 as a 2x2 matrix... we i=will determinant 0 ...what then

last wale question ka solution question 1 wale trick se solve kro to {B} option aayega ?

you are great sir

Super clarity sir

2nd question r3 interchange to r4

If the determinant of coefficient matrix is zero is then what about the number of solutions

What if the given Matrix is not orthogonal.. Can we follow the same procedure ? Can anyone please reply with my doubt

Sir take mechanical branch example....!!! They are little bit more complicated....

Methods are good enough but why bro so many ads

Method 2 is good sir Watching this precious video in 2022

Last question me orthogonal nahi hoga tab kya karoge??

thanks a lot ...so easy....

24:48 AS per your trick, option c also correct

Thank u so much sir

Thanks for your lecture it very helpful😍😍❤❤❤

32:22 at the starting u said for calculating Eigen values, sumof diagonal elements=sumof Eigen values.... But here the trick is not applicable Y?

Wtf i can solve Q2 in 2 seconds ... When a matrix has zero terms except it's diagonals then it's eigen values are the diaoganl terms itself

What if value of determinent of Q 1, is 0

What about if det=0.either no solution /infinite solution

Sir isko Kese Karna h vistar se samjhaiye

|A| not = 0 ok we get unique soln then suppose will this =o wht would be the answer

Genius sir Please help me to learn this

Nice tricks dear 👍
