Transformation Martices - IGCSE
acash09:
Hello everyone!
Hey i would like to ask ya ppl whether u have th transformation matrices for maths IGCSE?
E.G. for stretch: (in the attachments)
K is the scale factor and y axis as the invariant line
could i also have the one for shear ( x and y invar.) , rotation, and any others i didn't mention.
Thanks in advance!
Mohamed

hey
i used to have a wksht wid all of them
ill c if i can find it then ill send it to ya!
hopefully i have it sumwhere
Ghost Of Highbury:
reflection in ml y=x it's (0 1)
(1 0)
2. refelction in ml y=-x itz (0 -1)
(-1 0)
3. refelction in x-axis itz (1 0)
(0 -1)
4. reflection in y-axis itz (-1 0)
(0 1)
Rotation
1. rotation +90 degrees(anticlockwise) around centre(0,0) itz (0 -1)
(1 0)
2. rotation -90 degrees(clockwise) around centre (0,0) itz (0 1)
(-1 0)
3. rotation 180 degrees around centre (0,0) itz (-1 0)
(0 -1)
Enlargement
1. centre (0,0) wer k=scale factor, itz (k 0)
(0 k)
Shear
1. x invariant with x-axis wer k=scale factor (1 k)
(0 1)
2. y invariant with y-axis wer k=scale factor (1 0)
(k 1)
Stretch
1. x invariant with y-axis wer k=scale factor (1 0)
(0 k)
2. y invariant with x-axis wer k=scale factor (k 0)
(0 1)

sorry to say cudnt find it
but u got ur answer so enjoy
