Hi Could someone help me answer this question.. Describe a first-hand ivestigation to demonstrate the effect o a generated electric current when th strength of the magnet is varied. (Taken from HSC 2003 Q22) Thank you.

I don't know how to word it.. To find the quadratic eqution, we use x^2 - (sum of the roots)x + (product of the roots) = 0 Could someone help me out with finding the general formulae up to degree 4? x^3 ? (sum of the roots)x^2 ? (sum of the roots pairs)x ? (product of roots)=0 x^4 ...

i) Solve the equation z^6=0 using De Moivre's theorem and express the roots in the form a + ib ii) Find the fourth roots of -8-8(rt3)i and express your answers in the form a+ib. For ii) .. could you please use the mod-arg form, then using De Moivre's theorem method? Thank you

Hey thanks.. I've been doing a booklet of questions since 10pm..so approaching 4.5hrs now and i couldnt get those..so thanks! edit:you made a minor mistake when you expanded in question 2)..i think u shouldve got 2k^2 + 7k -4 =0 then you can factorise..thanks anyway

i) a polynomial P(x) of degree 3 has real coefficients and roots 2, 1+i if the leading coefficient of P(x) is 5. Find P(x) in the form ax^3 + bx^2 + cx + d ii) Show that there are two values of k, one which is integral, for which (x-k) dividies P(x) where P(x)= 3x^3 + (k+3)x^2 - (4k^2 + k -...

A stone of mass 0.2 kg was thrown horizontally at 20m/s from the top of a cliff of 19.6m. It strikes the ground at a certain istance from the foot of the cliff. a) Calculate the distance between the foot of cliff and the point of an impact of the stone with the ground: b) Calculate the...

I think you should drop chemistry or physics. You could drop one of them and concentrate on the other which would probably help with your marks. Good luck Let us knwo how you go!

Qantas for me.. But that's because I have tonnes of frequent flyer points so I usually get the upgrade to business

I'll sell you one of the crapper ones I have PM me

tyheres a comprehensive subject guide on one of the stickies called guide to selectingyour subject orsomething like that bro

Hey man, you rock!!

Okay..my bad.. but what I'm saying is that towards the end of July, he didn't even know what acceleration was (he even said he didnt know if the school offered it).. That just implied he was doing it for preliminary.. Everything just contradicts.. Okay..so he doesnt know...

] He didnt even know what acceleration was until 6months ago.. and he just happens to then go straight onto HSC Maths? Also, Timothy, I doubt your whole school just skipped the preliminary maths and went straight onto HSC..

Even if he isn't a fake.. He's still a spamming liar

because he's a fake !!! so anyway back to topic who here does accelerated maths?

Can someone please explain to me how Aquawhite is doing accelerated 2unit and 3unit maths when on July 21st, 2008, he asked what an accelerated subject was? That was on July 21st, 2008 posted by Aqua So..that means he somehow just finished his prelim and is going on to do hsc this...
