well transformation matrix is easy...
first we'll look at the identity matrix....it is 10
01
we'll make this matrix 2 coordinates...one on the x axis and other on y axis..... like (1,0) and (0,1)
reflection on the x axis= 1 0 reflection on y axis = -1 0 reflection y=x = 0 1 reflection y=-x = 0 -1
0 -1 0 1 1 0 -1 0

this will be done for rotation as well

for stretch learn by that stretch makes you "look kool"

"look" is matrix for x axis and "kool" is for y axis...... here "L" is 1 and "K" is the stretch factor...... I'm not so sure about shear... hope it helps :)

Relative velocity is that chapter which you can't study by yourself. Besides, if you don't get the concept from that Add math book, then other notes would be useless, most likely.
MY advice: leave relative velocity, practise other chapters instead.

in RV...u must master vectors first.... then remember this basic formula
Va = Va/b + Vb
by this make the unknown side the subject and add the vectors by tip to tail method....once ur diagram is drawn rest is easy....
important quatations
velocity of plane in still air = velocity of plane relative to wind
velocity of boat in still water = velocity of boat relative to river
course set by pilot/boat = bearing of relative velocity
