o_o woah nice. were any of the questions replaced?

wow 99 + fosho

you use the distance formula to calculate the distance between P and R ie sqrt[(3-x)^2+(2-y)^2] then u calculate the perpendicular distance between P and the line y=-1 and as yknow the distance PR is twice the distance P to line y=-1 you let sqrt[(3-x)^2+(2-y)^2] = 2 times (.....) sorry its...

for i) you let a point P (x1,y1) be the locus and do the perpindicular distance formula for both lines. ie distance=(4x1-3y1+2)/5 and distance=3x1+4y1-7/5 . you then equate the distances as it is equidistant and u get the locus of the point ii) is exactly the same reasoning

state ranking will get like 99 haha

do you have your mark from your internals yet?

85% hopefully

wing it

wow didnt realise it was so close!

is the first one just y= +/- x and is the second one just applying the perpendicular distance formula

haha thanks :D. btw are you the guy that harry keeps on talking about that makes up new methods for like every topic haha

hey do you have any tips for circle geometry? most of the time i have no idea where to construct the lines

kill that bitch marker

hmm maybe, it is one of my uac preferences. which courses are you gonna do :p

oh cool i go sunday. omg harder 3u circle geo is so retarded ><

woo harrys! cool guy

ya i go harrys! do u go on sunday or saturday

well if you ever come on sunday ill see you there! haha

i did ok lol 82% in 4u haha harder 3u killed me. when did you come to the sunday class?

aww i go on sunday haha. how was ur mx1/mx2 trials?
