To memorize the transformation is very hard, every O-Level candidate knows that. After seeing this video you will never be thinking about that anymore.

You are a master my friend. Am doing level 2 Further Maths in the UK, but just could not remember these damn matrix transformations. Your videos are fantastic, a real life saver, and I will be sharing with my friends! Have a great day

[@OLevelMathematics]

Thank you very much. Wait for other tricks I am going to share.

[@outspoken_rizz]

Wow Sir I found your video organically when looking for transformations!
Congratulations on the 12.3k subscribers and thank you for teaching me maths even now!

[@ZainabFatima]

veryyyy helpful, im so grateful to you for making these videos!

[@wafasarfraz3623]

Oh zaianb you are here wooooooooooooooo I guess you saw this vidoe for your o levels maths

[@hunterkiller1916]

Even though am watching it after 2 year ...i can still say its lovely😍

[@OLevelMathematics]

Thank you.

[@karafajanneh1065]

Thanks when you started with the sketch,it becomes so easy and I got to understand

[@shafisaif9103]

You literally saved my sorry life sir

[@OLevelMathematics]

Thank you very much. Glad to know that you have a thankful and Sorry-Free life now.

[@pythagoras1015]

Hey just wanted to say thanks a lot😣😍your videos are the reason why l got an A* in olevel maths. This is honestly one of the best study channels out there😍Really hope you would be making Alevel contents too😍

[@OLevelMathematics]

Glad to know it helped you.

[@arrafew2061]

Thank you so much for making this easy!
I can remember the rotation matrix formulas now ♥️♥️♥️

[@OLevelMathematics]

Have you checked the reflection matrix one yet?

[@OLevelMathematics]

Glad to know that. Good luck.

[@theturnertalkshow8334]

LISTEN, THIS IS THE BEST VIDEO ON RUclips

[@ap3xmath123]

I realy like this this has never been taught to me. Beautiful 🎉

[@theamateur6731]

Sir, what about translation and enlargement matrices. Please upload these also. And thatnkyou so much rotation and reflection matrices were extremely helpful. :))

[@razanahmad7519]

Thank you so much!!!! Really helpful

[@proshunsaha8757]

Thank you so much for the explanation sir. Hope to ace the quiz tomorrow.

[@OLevelMathematics]

Good luck

sir youare saviour

[@shaguftabilal1534]

i have my o level math p1 after 1 day and you just made things easier for me.

[@OLevelMathematics]

I know. Wish you all the best on your O-Level Exam.

[@hauntedbyrobots]

u r ... a king. THANK u

[@OLevelMathematics]

Wow. Thank you very much. I am glad it helped you.

Thank you soooo much

[@huzaifa6023]

very helpful

[@zainabmasood8460]

Thankyou sir.😊

[@nabirafatima2057]

Because of u I can get good grades....very thankful to u

[@OLevelMathematics]

You are doing all the hard work. Glad to hear I was the help you needed.

[@richworld5423]

There shouldn't be 90° as clockwise that is anticlockwise in 4th quadrant

[@aswinsubaskaran6470]

I was thinking the same icl

[@DaBestAround]

You lovely lovely man,

[@OLevelMathematics]

Thank you so much.

[@filzausman2563]

If the examiner gives us a triangle to rotate with any one of the matrix above, can we definitely say that the centre is 0,0? Or it can be any point for example (3,5)?
Do the above matrices only apply for origins rotations?

[@kaarimaconsignment8466]

yes it can be any point but for example, you only get the positional vector(1,2) by using the matrix,which is translation of 1 unit right and 2 unit upwards from the point that you have given(3,5) for the time being,you have to think the point as the origin.

[@brayan1621]

I’m trying to know how to memorize the rotation rules but I just cant

[@souvik492]

good trick but just remember sin, cos matrix Nah. you can put theta value for any angle transformation.
thank you

[@kaziyousra892]

elaborate please

[@straxsa]

can you elaborate?

[@edwardelric5921]

@@kaziyousra892 rotation matrix is given by
R=[ cos(t) sin(t) ]
[ -sin(t) cos(t) ]
Now, 1. For 90° ac rotation,i.e, +90° rotation,
R= [ 0 1]
[-1 0]
2. For 90° c.w. rotation, i.e, -90° rotation, (as sin(-90°)=-1),
R=[ 0 -1]
[1 0]
And 3. For 180° ac rotation, i.e, +180° rotation, cos(180°)=-1 & sin(180)=0. So,
R= [ -1 0]
[ 0 -1].
Replying too early 😜

What if it"s some other degrees say 60?what will be the solution?

You are welcome.

👏👏👏

[@umbra3324]

Are there tips for 3D rotation matrix?

[@myinbetween3851]

Me two days before an exam T.T Thank u so much!

[@OLevelMathematics]

You are welcome.

[@bilalmuhammad1547]

180 is anticlockwise or clockwise

[@filzausman2563]

It's the same thing

[@shyn12]

the 90⁰ clockwise rotation isn't clockwise rotation though.

[@aswinsubaskaran6470]

i was thinking the same thing icl

[@muhammadumer7365]

Hello Sir,
I am trying very hard to contact you through Facebook but still no reply from you. I really need help.
Please reply!!!

[@agriculture4life109]

Where is 270

[@tiffvnii2114]

i love you

[@fahadali3136]

Thank you sir this was disturbing me alot

[@emilyoyamo1033]

👍

[@icosagram]

easier way: don't use matrices lol
use a bivector, then you dont even have to remember anything

[@AhmedIbrahim-j9w]

I have a formula for them

[@OLevelMathematics]

Care to share it.

Guys i taught the indian guy
