That's not necessarily true... If you look at the software programs that have been developed to predict UAIs on previous UAC data, or even the Student Assesment Modeller (SAM) on this website it is quite easy to get into the 90s UAI range with only one or 2 band 6 and the rest band 5 but that's...

Anytime.. That's okay, lol i hope those answers are right... lol but yeah not being there when you started trig equations would just about do it to you.. :D

SOLn t = tan A/2 I got tan A = 2 + root 3 or 2 - root 3 so.... A = 75 deg. or 15 deg. Could be totally wrong tho... 3cosA + 4sinA = 1 let t = tan A/2 3 ( [1-t^2]/[1+t^2]) + 4 ( 2t / [1+t^2]) = 1 3 - 3t^2 + 8t = 1 + t^2 4t^2 - 8t -2 = 0 t = 8 + or - 4root6 / 8 A/2 =...

SOLn I think some of your math's question for the inequality with an unknown on the denominator did not display properly - if you meant.. x + 1 > 2 ...........---- ...........(x-2)+2 Then SOLn is x > 1 or -2 < x < 0 I couldn't quite be bothered working the other one's out now...

Ahh ok.. i know what i did wrong now It's ok i just forgot to invert the signs i.e (x-3)(x+1)=0 x= +3 or -1 i was using -3 or 1 so that was giving me the wrong answer but it's k now... thanks for your help :)

How'd you get that? Do you solve that by squaring both sides... or do you do two cases?

Extra Question I added an extra question there.. maybe u can help me with that one tooo :)

Haha LOL they aren't triangles tho..... u mean cyclic quadrilaterals don't u? Also, while we are at it: I don't have the soln to this previous exam and i don't know if i've answered this right so you might be able to help me... 3 ------- < or = x x-2 I got: 1 <or= x <or=...

Explanation Plz... Are you using the cyclic quadrilateral external angle property, and how does that prove that those points above are a cyclic quadrilateral? Wait nevermind, lol i just figured out how you did it, yeah that's using cyclic quad ext angle. Thanks, i can never see which theorem...

Added Drawing Thanks for the advice, did a rough sketch in paint.. do you have any idea how to get the solution?

Sorry for lack of diagram, my printer blew up when we got hit by lightning perhaps someone can find a solution to this question? Two intersecting circles meet at F and C. The points B,C and D are collinear, the three chords produced from these points; BG, CF and DE are concurrent at A. Show...
