wat do u study for in ur maths hc trials
cuz teacher didn't say much
This is for 5.3 maths (advanced)

 

[xXmuffin0manXx]

quad, prob, con, graph, SA + V, Stat, Sim., Trig, Algebra,

 

[-tal-]

Know your constructions, (bisecting angles etc), probability, and those stats tables, basic algebra

Don't forget the stuff on Imaginative numbers...Eg. Finding the square root of -3

root 3 :uhhuh:

 

[tommykins]

root 3 :uhhuh:

No.

It's sqrt3 i.

 

[xXmuffin0manXx]

No.

It's sqrt3 i.

lol..no comment..

(notice the :uhhuh: )

i was being sarcastic =.=

They should really build a program that detects sarcasm via teh intraweb.

 

[fullonoob]

No.

It's sqrt3 i.

does the " i " stand for imaginative???

lol your mup...copy using this site
I already told you look through past sc papers and basic year 9-10 questions.

You're doing 2U Maths and talking about complex numbers. You must be cool.

/sarcasm

does the " i " stand for imaginative???

Yeah. More correctly, it stands for the square root of -1.

LOL.

For SC, I didn't do any study for Maths and scraped a high band. Same with computing, highly competent lmao. The only study I did was for Geography, where I failed the half yearly (35%, no study), and got a mark of 88 for Geography in the SC. TAKE THAT 35% lol.

Remember kiddos, don't stress about the SC, it's only year 10. The only thing I benefited from the SC was the experience of the BOS people patrolling and giving instructions, which will be helpful for the HSC.

Yep, but we don't necessarily define "i" as the sqrt of -1, it's more so i² = -1.

 

[tacogym27101990]

dont bother with study for sc
its a waste of time

 

[Continuum]

Yep, but we don't necessarily define "i" as the sqrt of -1, it's more so i² = -1.

Yeah, my bad.

It's because i can refer to +sqrt(-1) and -sqrt(-1) isn't it?

 

[tacogym27101990]

no -sqrt(-1) would be -i

 

[tommykins]

Yeah, my bad.

It's because i can refer to +sqrt(-1) and -sqrt(-1) isn't it?

-sqrt-1 = -i

I really don't know why, but I've read it numerous times that the definition of i is that i² = -1.

 

[Continuum]

no -sqrt(-1) would be -i

http://en.wikipedia.org/wiki/Imaginary_unit#i_and_.E2.88.92i

If you put i=-sqrt(-1), then i² would still be -1 wouldn't it?
