Ey ppl!

 

I'm gonna be taking a break from LF for about a week or two. I've got 4 mid term exams coming up in the next couple of weeks.

 

One of them is tomorrow for maths. (2nd hardest)

 

The next day is for English (2 hour exam for an essay on a book).

 

Next week, an exam for Specialist maths (the hardest maths).

 

And then following that week, an exam for physics (the topic of sound).

 

Yep, that's why I need the time off to study and have no life. :(

 

While I'm gone, wish me luck!! (I'm gonna need it!!), be good, behave, don't talk to strangers and take it easy. See you all soon.

 

Well, time to go back to studying.

 

Cheers. :cheers:

That's cos you're the admin. If you're not here, the forums turn upside down, lol.

 

I also need very high scores to get into the course I want to do. That's why I'm not gonna have too much free time.

 

Anyway, thanks guys, now it's back to studying Vectors.

you know what you need? first of all, a pair of scissors, a jar of mayonaise, one copy of the oxford dictionary, and a mexican named pedro.... i mean... dammit. i got nothing. good luck!

 

o/

 

P.S. the above is a little man going High 5. the reply to this is \o, so none of you ask bad questions.

 

:D

Thanks for it all ppl! And good luck to you too sabertooth!

 

God, had the maths one today (the second hardest one). Wasn't too bad, but I'm more worried about the hardest maths one. Are there any mathematicians out there? Can someone please explain to me how the hell this question works?!?

 

If z = x + yi and z = {square root}(-5 +12i), then the values of x and y respectively are:

 

A: -3 and 2

B: -2 and 3

C: 3 and 2

D: -3 and -2

E: 2 and 3

 

The correct answer is E, but how the hell does it work?!?! Can someone please explain this concept? This is confusing me and making me dizzy! :confused:

 

Cheers.

[align=center]z = x + yi

&

z = {square root}(-5 +12i),

 

1. Ok, I think I remember this. The SQRT of (-5 +12i) is worked out by first breaking down the numbers "-5" and "12" to -2*3 and 2*2*3. Then you take the pairs that are in those numbers and move them to the left side. Look at what they are! 2 and 3! Coincidence? I think not! We still have a -2 in the SQRT bracket though. But a - SQRT cannot exist so it is an imaginary number, which is what the, "i" represents. So that -2 turns into an i and is moved over to the left side as well

 

So,

 

z = x + yi

or

SQRT of (-5+12i) = 2 + 3i

[/align]

 

 

 

Eh, I most likely have that wrong... but oh well, I can't remember and I tried. :D

Holy Crap Rhett!! That looks pretty damn good! :thumbsup:

 

I understand what you mean by the 'breaking down'. Of the integers.

 

Eg: -12 = 4*-3

 

Square root of negative 12: 2(sq}(-3)

= 2{sq}(3)i

 

That makes some more sense, thanks heaps Rhett :).

 

EDIT: Another question. i as we know is an imaginary number. My question is that if i^2 = -1, which is a real answer, is i therefore entirely imaginary/impossible? There must be some realistic aspects to i. What's your opinion? Am I right or do I need a break :S. Cheers again to Rhett and everyone.

They aren't really "imaginary", it's just that they do not exist in the real number set. Sometimes the easiest/only way to compute something, even if you start out with real numbers and the answer is a real number, is by using imaginary numbers.

 

They're used in conjunction with real numbers to spit out a real number, get it? Even fractions do this in one way or another.

 

The only direct usage for them I can think of is when measuring currents and things like that but as I explained in the previous paragraph, they're very useful in that particular way.

I've got two weeks to study before I take the "Dakota Step" test. I took a practice Math test today, and got my *** beat by algebra equations.

 

Here's hoping this "FlyingDAWG" pulls an ace out of his hat by that time, or else going into the senior grade next year will look pretty bleak. :(
