hi Viewers plz dont get confused with the formula written for anti clock-wise rotation. In the derivation i have used [x y] (row matrix) in the the matrix multiplication In the problem i have represented (x,y) as column matrix in the matrix multiplication. in the both cases formula is x'=xcos(theta) - ysin(theta) y'=xsin(theta) + ysin(theta)
Those who are saying that formula is wrong for clockwise and anticlockwise, please check it again. It's absolutely right. If we are rotating in anticlockwise direction then -> x' = xcos(theta) - ysin(theta) && y' = xsin(theta) + ycos(theta). Which is absolutely right according to the above matrix. I know you can right matrix theta matrix first or second and depending on that it will change.
Sir please Upload lectures on Different color Filling technique like scan fill, Boundary fill, and flood fill and please also try to cover topics like Clipping in which Cohen sutherland algo, and polygon clipping like sutherland hodgeman and Weilar artherton algo.
Sir, the formula that you derived in your perivious lecture for anticlockwise has negative sign in 2nd row 1coloum but here you have written it with 1row 2nd coloum... Thankyou for your lectures they are very helpful for us. Thankyou sir..
hi mishra based upon order of matrix we need to represent the formula. here the formula is important than matrix . so please once do the multiplication and see the formula both will be same. thanks for your interest towards our channel and your support.

Hello Sir , Thanks for this tutorial it's very easy to understand . I am little bit confused in one question please clarify here. Q. The coordinates of square are given as (0,0) (2,0) (2,2) (0,2). Scale the square by a factor of 2 in x and y direction and find new coordinates of square. Ans : Sx= 2 & Sy = 2 . is it right ? According to the above question ..
hi deepak yes in the given problem Sx=2 and Sy=2 here both the scaling factors are same so the scaling will be performed uniformly and shape doesnt change. scaling factors are > 1 so the size of the square will be increased. hope your doubt has been clarified.
Consider a triangle A(0,0), B(1, 1) and C(5, 2). The triangle has to be rotated by an angle of 45o about the point P(-1, -1). What shall be the coordinates of new triangle?(ugc net 2015) OPTION A A′=(1,2-√−1),B′(−1,22-√−1) and C′=(32-√−1,922-√−1) OPTION B A′=(1,2-√−1),B′(22-√−1,−1) and C′=(32-√−1,922-√−1) OPTION C A′=(−1,2-√−1),B′(−1,22-√−1) and C′=(32-√−1,922-√−1) OPTION D A′=(2-√−1,−1)B′(−1,22-√−1) and C′=(32-√−1,922-√−1) sir can you explain it or post an example video on rotation..
hi rohit just follow the steps so that you can get the solution 1) translate all the points to the origin from the point (-1,-1) 2) rotate all the points with an angle 45 3) translate back all points to the original position .

Hi shubham gupta if we want to rotate an object about any arbitrary point then follow the steps 1. Translate back to origin ( given point (30,30) ) have to translate with parameters -30 , -30. 2. Now object will be with respect to the origin so perform rotation with given angle 3. Now again translate back to original point ( translation parameters 30 and 30 )
hi sanjay plz dont get confused with the formula written for anti clock-wise rotation.

hi shivam yes one parameter can be greater than 1 and other less than 1. that mean it is not a uniform scaling and there will be difference in shape and size of an object. hope your doubt may be clarified.
In the anticlockwise rotation example, can we say x'=-y and y'=x and for the clockwise rotation example x'=y & y'=-x ????.. so that every time we don't have to do the matrix multiplication... Will it be correct??
hi sai ram based on matrix multiplication i have changed the order.formula has not been changed. once check the formula by performing the matrix multiplication. hope your doubt has been clarified.
hi raghi based on the formula we have to write the matrix that means depends on order of matrix also we can write the logic. so instead of following the matrix just follow the formula.
hi anjali thanks for wacthing my sessions. here in my video i have written the formula and while solving the example based on matrix multiplication i have changed the order but formula was not changed. Hope your doubt has been clarified.
Show that two successive reflections about a line passing through the coordinate origin is equivalent to a single rotation about the coordinate origin. Sir plz helo me to solve this question . I understand that two successive reflections means line become in 1st quadrant again then rotation of that .am I right or wrong plz sir give full explanation on this question.
hi bharti sharma consider any small object and apply the following first perform the double reflection Second rotate the object with an angle of 360 with respect to origin. both the results will be same.
Sundeep Saradhi Sir double reflection about coordinate origin that means line came in 1st quadrant after double reflection then I should rotate it at 360 degree. Am i right or wrong?
in previous video of 2d-transformation u said that,if Sx=Sy,scaling will be donw uniformaly,but in this video u r saying that if Sx=Sy then no change in shape. please explain what happening here?
Hi Rahul here scaling is used to change the object's shape or size or both in some cases. 1) if Sx=Sy the shape doesn't change but size may vary and if Sx & Sy are in b/w 0 & 1 then the size will decrease otherwise size will increase. 2) If Sx not equal to Sy then shape and size both will change. hope your doubt has been clarified..

Rotate the rectangle (0,0), (2,0), (2, 2), (0, 2) shown below, 300 ccw about its centroid and find the new coordinates of the rectangle Sir plz solve this with ur method i"m not getting desired answer
Priyanshu, the coordinates you mentioned makes a square not a rectangle. As we've to rotate the square by 30" in counter-clockwise direction, then the rotation matrix would be: [cos30" -sin30"] = [ sqrt(3)/2 -1/2] [sin30" cos30"] [1/2 sqrt(3)/2] Thus, the respective coordinates are: (0,0) -> (0,0) (0, 2) -> (-1, sqrt(3)) (2,2) -> (sqrt(3) - 1, sqrt(3) + 1) (2, 0) -> (sqrt(3), 1)
dear sir , just a suggestion that please make proper editing in your videos before uploading, like you show rubbing the board can be cut and drawing of graphs can be cut to show the final graph. Don't get annoyed just a suggestion
But the editing of educational videos would make it very hard to watch. Cause it will always reduce the learning experience quality of the video. However, it is a lot shorter than our boring classes in the classroom.
or u can just press L at that time if u are using PC or double tap the screen if you are using smartphone.. Why shall he waste the time in editing videos when he can make one or two more videos at that time.. :) PEACE!
hi saurabh can i have the correct formula from you so that i will update it in our video and i will not delete the video as some one said it is wrong. and of course i am not confusing or misleading the students with wrong formula and if i found it wrong immediately i am updating with correct one. you can see the comment sections with updating comments for the mistake in the video. Waiting for the correct formula from you.

Sundeep Saradhi ok got it sir
Use earphones and watch in 2x to save ur time. Anyhow, it's a brilliant video
4:15 Translation
11:35 Rotation
24:46 Scaling
Those who are saying that formula is wrong for clockwise and anticlockwise, please check it again. It's absolutely right.
If we are rotating in anticlockwise direction then -> x' = xcos(theta) - ysin(theta) && y' = xsin(theta) + ycos(theta). Which is absolutely right according to the above matrix. I know you can right matrix theta matrix first or second and depending on that it will change.
Then
Then why the previous videos the for mular of clockwise and anticlockwise says otherwise
Yes you are correct
One of the best explanation i found on youtube..Thanks Sir
Sir ,Rotation formula is taken wrong , you have written formula for clockwise and solving for anticlockwise
compare it with previous one both are same but in different format simplify and you will get same formula
You are right aditi.
Sir you make us confused!
The graph that has been plotted at 17:02 is wrong. (-1,1) is plotted incorrectly.
Fantastic Awesome Wonderful Explanation 👌👌👌

Hello Sir , Thanks for this tutorial it's very easy to understand . I am little bit confused in one question please clarify here.
Q. The coordinates of square are given as (0,0) (2,0) (2,2) (0,2). Scale the square by a factor of 2 in x
and y direction and find new coordinates of square.
Ans :
Sx= 2 & Sy = 2 . is it right ?
According to the above question ..
hi deepak
yes in the given problem Sx=2 and Sy=2
here both the scaling factors are same so the scaling will be performed uniformly and shape doesnt change.
scaling factors are > 1 so the size of the square will be increased.
hope your doubt has been clarified.
Consider a triangle A(0,0), B(1, 1) and C(5, 2). The triangle has to be rotated by an angle of 45o about the point P(-1, -1). What shall be the coordinates of new triangle?(ugc net 2015)
OPTION A A′=(1,2-√−1),B′(−1,22-√−1) and C′=(32-√−1,922-√−1)

Sir anticlockwise of clockwise mai sign glaf liye hai sine k plz correct that.
hi vishvesh
depends on the order of matrix we need to write the formula.
if we want a rotation not by origin but by another point let say (30,30),then what to do
Hi shubham gupta if we want to rotate an object about any arbitrary point then follow the steps
1. Translate back to origin ( given point (30,30) ) have to translate with parameters -30 , -30.
2. Now object will be with respect to the origin so perform rotation with given angle
3. Now again translate back to original point ( translation parameters 30 and 30 )

Sir in rotation formula for anticlockwise is changed. U r using clockwise formula. How its possible.
hema jeya bcz of change of matrix
Thank you very much Sir
thank you
(Perform 90° rotation in a unit cube.)
i think it is 1,1 as it is a unit cube. not perfect but i think.
Thank you so much sir for your reply
can Sx be greater than 1 and Sy be less than 1 or vice versa?
hi shivam
yes one parameter can be greater than 1 and other less than 1.
that mean it is not a uniform scaling and
there will be difference in shape and size of an object.
hope your doubt may be clarified.
Sir, I am confused bcoz earlier you showed us anticlockwise formula, now u are using different formula.
hi Faisal
formula will depends on the order of matrix which we are considering.
Sir! in place of counter clock you used clockwise formula.
bcz of change of matrix and dont see the matrix apply the multiplication and check the formula. we are writing the matrix based on formula.
Sarosh Faisal Khan exactly
In the anticlockwise rotation example, can we say x'=-y and y'=x and for the clockwise rotation example x'=y & y'=-x ????.. so that every time we don't have to do the matrix multiplication... Will it be correct??

i find mistake in Ty in square how it will be 3 it is 2 na from origin ???
Show that two successive reflections about a line passing through the coordinate origin is equivalent to a single rotation about the coordinate origin.
Sir plz helo me to solve this question .
I understand that two successive reflections means line become in 1st quadrant again then rotation of that .am I right or wrong plz sir give full explanation on this question.
hi bharti sharma
consider any small object and apply the following
first perform the double reflection
Second rotate the object with an angle of 360 with respect to origin.
both the results will be same.
Sundeep Saradhi
Sir double reflection about coordinate origin that means line came in 1st quadrant after double reflection then I should rotate it at 360 degree.
Am i right or wrong?
yes exactly. all the best
Sundeep Saradhi
Thank u very much sir.
Nice thanks
Thank You Sir.
in previous video of 2d-transformation u said that,if Sx=Sy,scaling will be donw uniformaly,but in this video u r saying that if Sx=Sy then no change in shape.
please explain what happening here?
Hi Rahul
here scaling is used to change the object's shape or size or both in some cases.
1) if Sx=Sy the shape doesn't change but size may vary and if Sx & Sy are in b/w 0 & 1 then the size will decrease otherwise size will increase.
2) If Sx not equal to Sy then shape and size both will change.
hope your doubt has been clarified..
yeah..i had confused when u written there Sx=Sy,no change,and in previous video that Sx=Sy,uniformaly change.
thanks..sundeep sir,,i have my inetrnal exam on 17th april,it helps me a lot

thank you sir..
Thanks bhau
The results wrong because you have applied clock wise formula for anti clock wise relation, and clock wise formula for anti clock wise direction

hi diljeet

Great
Sir you made a mistake .in rotation 1st example says that anti clock wise direction but you follow the clock wise direction and results is other .

Sir plz solve this with ur method
i"m not getting desired answer
30 degree
Hi Priyanshu
send me an email to askme.selflearning@gmail.com
so that i will send you the solution as a reply to your mail.
Priyanshu, the coordinates you mentioned makes a square not a rectangle.
As we've to rotate the square by 30" in counter-clockwise direction, then the rotation matrix would be:
[cos30" -sin30"] = [ sqrt(3)/2 -1/2]
[sin30" cos30"] [1/2 sqrt(3)/2]
Thus, the respective coordinates are:
(0,0) -> (0,0)
(0, 2) -> (-1, sqrt(3))
(2,2) -> (sqrt(3) - 1, sqrt(3) + 1)
(2, 0) -> (sqrt(3), 1)
