Have you ever(the world was created on the day after your trials) tried getting advice off your teacher?

I want to do statstics.. hmm will learn it right after the HSC

Since he mentioned not anything about a calculator, I guess fatmuscle must have had an implant, you cheat! :D you don't really need protractors and strings. what you should get is a template with the curve y=x^2, coz you probably will have to draw a parabola for 2 unit.

this is an easy question, just looks messy coz it's typed up here

i) hmm it's takes ! 2 mins to reach O, so it should take B 2 mins to reach ) too.. so V = 0.5 km/min ii) imagine a cartesian plane with origin at O. now, A's position is (-2,0), B is at (0,-1) initially their position at time t will be A( (t-2), 0) and B( 0,(Vt - 1) ) so the...

maybe the general maths forum? they have stats

Your maths teacher is the best study guide.. he/she knows what your weaknesses are

if I hear one more comment about curve sketching being easy!

you have a booklet for each question initially, then hands up for extras

ofcourse you know it. that was for povodude

complicated.. just take conjugates of both sides like stag_j did

soryr, differential equation :p for example if they give you something like the resistance is proportional to the velocity of a particle which is also subjected to gravity, then you write the D.E. y'' = -g - ky' (or a= -g-kv) where k is a positive constant. then work from there.

check page 177, 178 of the *ahem* coroneos supplement :p EDIT: to save you time digging that book out: page 177 SECTION 15 - ANGLES IN CIRCLES THEOREMS 2.) ANGLES IN THE SAME SEGMENT OF A CIRCLE ARE EQUAL

you can state equal arcs subtend equal angles at the circumference of equal circles. phone the HSC advice line if you want to make sure

go to UAC's website, scaling/UAI get table 3 or the full report, there will be a table that converts raw marks to scaled

equal arcs do... the chord thing is a bit tricky, because in general, the angle that is subtended on the major arc is different to the one subtended on the minor arc

Try not to think resisted motion as something different from erh 'normal' motion. it always, write your D.E. then integrate or solve.

yes you do have a greater chance if you change

actually it's because when there's excess H+ the cathod reaction effectively becomes O2 + 4H+ + 4e- -> 2 H2O E= +1.23 Volts as compared to O2 + 2H2O + 4e- -> 4OH- E = +0.40 volts
