I don't know what's wrong with it... But I mean there HAS to be something wrong... Maybe I'll show my teacher tomolo.. hehe oh I just remembered I've got this other one: i = root -1 i^2 = root -1 * root -1 = root (-1 * -1) = root 1 = 1 hehehe :p :p but u see...

cool! :lol: :wave:

Hey people! :wave: you know in the chem monitoring and managment topic how they ask us to describe tests for various cations and anions, do u think we need to know those two tables in conquering chem? ( sorrie I don't have to book with me for the exact pages) or can we just say that they use...

But in physics we DON'T do conical pendulum!!! The only thing I think that might relate physics to 4 u maths is projectile motion. But the physics questions are so easy! all you do is just substituting numbers into your formulae. You should look at the fitzpatric questions on projectile...

some one showed me this proof which proves -1 = 1. And I can't figure out whats wrong with it... -1 = -1 -1/1 = 1/-1 root ( -1/1) = root (1/-1) root -1 / root 1 = root 1 / root -1 i / 1 = 1 / i cross multiply... i^2 = 1 -1 = 1 :chainsaw: :jaw: :wave:

I do both physics and 4 u maths but I don't think they really help each other... Cause they took out all the maths in the physics course, yay:D :cool:

Mine changes from physics to chemistry to 3 u maths... but right now it's physics!!! :D

That's the option that we are doing and I asked the teacher this question and he said the book (by Sam) didn't show the difference, just saying that they are. I don't have the book my self so I don't know whether this is true or not...

ok well I've got a question: What's the difference between an object orientated program and an even driven program? Which one of these is VB 6 ? Why? (my teacher can't answer this, he's so crapy!)

I don't believe in turtoring. Take 4 u maths for example, I'm the only one in the class who don't do any turtoring and I think I'm gonna come second or third in the class. I mean, I look at all my friends, and all I see is that their turtor gives them LOTS of exercise... and I can get that...

I think my teacher said that they have to send in all our school assessment results to the board of studies by 17/ 9 or something... Like I'm still thinking of dropping 4 u maths even though i've done the trials and so I guess I better decide b4 that day so that they can send in a 2 u mark for...

I agree perms and combs is the HARDEST topic!!! Somehow with every question, I can think of like 4 or 5 different ways of doing it and I always get a different answer each time. How am I suppose to know which one is right??!!! I mean, when I was thinking about it, they all sounds right... :(

hey we never learn that at school!

how did u get that equation, y = kx(R-x)? and what's k?

hi Skandi, thanks for trying to do this question for me. But I have a question, when u say x = 1/2 R, y = 1/2 [V^2sin^2]/g, ( I changed ur R's into V's... ) how did u get the next line after it?

A body is projected from a point on a horizontal plane reaches a greatest height h before hitting the plane R metres away from its point of projection. Show that the equation of the body's path may be expressed by y = [4hx(R-x)] / R^2 Somebody PLEASE show me how to do this question!!!! I've...

Chem doesn't really suck. Sure it might gets a bit boring somethimes but ANYTHING is easier then SDD!!!! (just had our trial today, it was 100 times harder then the BOS specimen paper that I did for practice, I didn't even attempt a 10 mark question and I've never done that b4 :(

Is the answer for this B or C ??? Cause I know that the succuess one saids it's B but somewhere else it said it's C...

um. i'm kinda choosing between nsw and syd. Everyong says nsw is the BEST engineering school but I personally like usyd as a whole... But then the uai is lower for nsw so i guess it takes off the pressure which is good! :D ( like 79 vs 91!!! the system doesn't make sense) But then most of my...

you know you can always try numbers... like if you want to know what happens when x approaches 3 on the + side, you put into the equation a number like 3.001 and work out the y value on your calculator. In this case you get 47.67.... so u can sorta tell that the y is getting bigger. so u can say...
