... That question

Ambiguous

^ spiral and exploitables method or tan(45-30)

^ wtf lol By eliminating a factor of the denominator, you have altered the domain of the original function, thus making it a new function. Is there some fancy explaination?

Cool link.

I can't think of why cis = e^ix Someone tell me

okay if you just started, then the thoughts you should have are: (2+i) is a root, if I sub it in LHS will =0 Next, after the expansions you will have a BIG complex number. RHS says it's 0, therefore the real part is 0 and the imaginary part is 0. By doing so, you will get some function...

If you're don't like memorising, derive it then. How you say? Read that guys post ^ Ignore the double angle bit. Think he meant trig expansions

You spend too much time helping spiralflex. Have you noticed that?

I wonder what the challenge questions in MIF are like lol! Haven't started revising so dunno

looks like you put it in then equate the real and imaginary parts =0. Then you might need to solve simulatenously. Sorry for not doing the question lol

Re: Massive terrorist attacks in Norway, over 30+ dead Dunno about christians but the Islamic terrorists only do what they do because of religion, i.e. for God. ^lol at sarcastic posts Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not...

Justice and religion...lmao Was that meant to be a reply to some post I've made?

It sounds like arj1 would lol

Not always if you want to maximise your atar... I'm sitting on over 10 units

AO is the diameter of the smaller circle. AB would intersect the smaller circle once at C

I should yes. I don't want to devote too much time on this subject unfortunately Good luck with your external. If you don't get higher than me I would be whaaa?

Really simple, diameter subjects a right angle, then prove ACO congruent to CBO

I'm comming first...the externals I've looked at are a joke to be honest. Some open ended questions are becomming a bit prevalent

Alternatively...use parametrics[parabola part] Parametrics suck...
