I think u've to learn it in fact it requires rote learning

 

[Gémeaux]

no i never learned it.. one cud undrstand it too.. but i dun thnk id b able to xplain it in rytng =/
for stretch learn stretch makes u look kool. look cums first so itx fer x-axis invariant n kool fer y-axis as invariant lyn. look means
1 0
0 k
and kool means
k 0
0 1
where k is the stretch factor
hope it helps

oh and start each tym from the basic identitiy matrix
1 0
0 1
i prefer to draw a small grid on a syd of ma page, mark the co-ordinates (1,0) and (0,1) and apply the transformation on them.

 

[Gémeaux]

for enlargemnt its
k 0
0 k
(kook) bcuz wen u plot (1,0) (0,1) the zeros on axis wont chng wich means 1 wud be multiplied with the scale factor for itx enlargemnt. both the 1s wud move along their respective axis according to the scale factor.

this works for all transformations.. specifically reflection and rotation.
eg
1 0
0 1
will become
1 0
0 -1 wen reflected in x-axis only bcuz the co-ordinates (1,0) will not chng being on the inv. and (0,1) is reflected to give (0,-1)

thnnx aloot got the basic concept of it.....

 

[Gémeaux]

ur welcum =)
