hope it helps

thanks, but i really didn't understand :[ if i could have some sort of visual material to look at it'd be really helpful.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
hahahahahaha....and what if it comes...I am quite good at the rest...well thanks for the help...I think I'll have to ask my teacherRelative 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.
are you even serious ?? this is an quadratic equation...u don't know how to solve it ??4024/21/O/N/2010

I have problem in the last chapter that is relative velocity... its so damn confusing!!! especially interception questions!
in RV...u must master vectors first.... then remember this basic formulaVa = Va/b + Vbby 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 quatationsvelocity of plane in still air = velocity of plane relative to windvelocity of boat in still water = velocity of boat relative to rivercourse set by pilot/boat = bearing of relative velocity
ok then..we are add maths they are not..explain or dont ... dont insult anyone or pick up a fight...-__-
good tips...worth it...
I know how to solve quadratic equations ! I have never had problem in this ..i even got the answer to x but cant make the equation and reduce it to x^2 +34x-225=0for solving quadratic equations
aX^2 + bX + c = 0
use the quadratic formula:
b +/- (b^2 - 4ac)^1/2
2a
And 'symbolic' and 'numerical' integration and differentiation are different...well....which calculator u got u gotta check it first.... calculator with graphic display and symbolic integrations are not allowed...ur the lucky one if the invigilator doesn't take it
