hey thanks a lot shan....

@priceless and reishamix

i wud like to learn the base vectors method ..plzz.

it wud very kind of u to teach me..
thank you

Lol ya sure np. umm ok here v go.

Reflection:

1. 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)


phew don't LOL i no itz a lot but once u no dem itz rely easy. u can du ur sums very easily den widout doin da point co ordinate thng. once u no wat da transformation is eddie_adi619 u ll no wat da matrix is also. gud luck 2 all 4 ur xams hope v all du well.
Don't say "God I have tooo many problems" but say "Problems I have God!"   Gud Luck 2 all 4 xams. Hope v all du well.....fingers crossed LOL

have to say lol  ;D

when it is parallel to x axis, then y axis is parallel
and vice versa

but then howcome
how come in shear

when it is parallel to x axis, x axis is invariant. how :S??????

im sory but wat du u mean wen itz parallel 2 x-axis den y axis is parallel. hw can both axes b parallel? lol im sooo confused n bout da base vectors dey r da matrixes i wrote down-dey r called base vectors cuz dey r da same evry tym but shear n stretch just duznt go in2 my head AAAAA LOL ??? :-\

hey..the ones whu dint quite understand the inverse methos to find the transformation matrix...it can also be don't with the help of simultaneous equations..juz multiply as if the invariables wer numbers wich wil giv yu the equations thn solve..:D
