Wrong Matrix Multiplication .. 3X3 matrix cannot be multiplied by 1X2 matrix

[@shashank6803]

dont multilply with 3D do it for 2D

[@nishantahluwalia7958]

@@shashank6803 still wrong. the third value corresponds to the 3rd plane.

[@alvinaafsheen8874]

so there is no need to do it 3x3 matrix we can do it by keeping it 2x2 ?

[@gravity3252]

its not a 1x2 matrix ,we have to write it as 3x1 matrix

[@simrankumariofficial4118]

Mam is it necessary to take identity matrix in (3*3) form?? ... Can we not find reflected position by using identity matrix in (2*2) form???

[@Ashutosh18singh]

Everything is right here except she should have taken [ 3 4 0] matrix which is of order 1x3 to multiply with reflection matrix to get A pt coordinate after reflection, similarly in the cases of B & C

[@nishantshrivastava8937]

Or you can use the matrix of [1 0]
[0-1]
In your formula

[@gravity3252]

it would be [3 4 1] , not [3 4 0]

Ma'am, reflection about the origin, about y=x, y=-x and y=mx+c are also parts of the syllabus .

[@vivekkardam5921]

Hii

[@vivekkardam5921]

About y=x,y=-xand y=MX+c

How could you multiply a 2x2 matrix with a 3x3 matrix? 🤯🤯

[@mohaksharma6327]

Shi bola bhai yar fucks h yeh teacher

[@bharathkumar849]

Same doubt bro.
How we can do with homogeneous matrix?

[@devashish8970]

3x3 bna dia 1,1,1 assume krke

[@kanganagarwal]

That's what I was thinking 🤔

[@learnmoregamingbs1231]

Actually 1 0
0 -1 this much is enough no need to take 3 row and 3 column I am here after a year so I assume you have already cleared the doubt

[@sinaithi95]

this matrix multiplication is wrong wrong hai ye

[@archanarv7354]

Mam i have a doubt. Why there arises 3x3 matrix.

[@mohdtarique63]

Ma'am scaling Wali topic kahan hai

[@kalavakurisrikanth9601]

Mam is it possible to perform 2 d matrix with 3d

[@alokitwilson9296]

1Kth LIKE FROM MY SIDE.😄😄

[@mayurkumawatmusic]

i don"t understand why their is any need of taking 3x3 matrix and even 1x2 cant multiply with 3x3 matrix , but even though it was a great video ma'am :)

[@sinaithi95]

yeap i figure it out too i deduced my own formula for that reason

Can you please provide me the playlist link for computer graphics series mam?

[@Malaysingh65]

Bhai z cordinate ko zero Maan lo

I told my friend your channel...❤

[@pushpaveerappan2646]

Thank you so much mam July 6 enakku computer graphics exam very useful your video Mam

[@nyambelilonga555]

Thanks madam....I really appreciate your work .May you consider preparing videos for all modules in ICT.

your 21 video has some defect and buffering

[@shadmansajid9226]

Sometimes, You skipped important part . You have to practice more . Then you can teach others. Teaching rating is 40/100. You need improvement .

[@MadMaXxFx]

Some of the videos are showing as private videos, pls fix that

[@omprasadnarute9111]

👌👍✌️

This matrix multiplication is not possible

[@skillradius9867]

The b should be 3,4,1
