Without the equal sign we don't have an equation. We just have what's called an expression. An expression is arbitrary - it can be anything, so we have no rule for it.

An equation forces one variable to be strictly defined, or form a relation between two or more variables. This is why it must be present to form a graph.

(Or at least something similar to an equal sign. The < symbol will give us an inequality)

Has anyone here learnt a topic called the unit circle where you know the exact values of the trig ratios and where you learnt the fundamental formula (I.e. +k360)

I can now anyway! I went to a pretty decent 2U lecture on Trigonometry on Monday, lecturer was pretty good, think his name was James, or, Jameen, or something...  ;)

Hey! That was very algebra intensive and required the use of trig identities; I'm sure there are heaps of ways to get to an answer, some of which will be quicker than mine. Still, when all I really did was sub in a bunch of identities, brute force doesn't take too long!


I also didn't get to the final answer (ie. what x/theta actually is); I'll leave that to you

Damm, it required that much working out. Woah, you guys are awesome. Cheers  ;D

COuldn't of you have divided by 3 first?

That would've made the factorisation process suck

Also if you think that's a lot of working out, check out the Ext 2 qn thread :P

Jake what is that typing program you use to type up the answer to the question?

It's a nifty little program called Word; I suck at LaTeX (at least when it comes to slightly more complicated stuff, or typing quickly), so I prefer to use Word, screenshot, upload to Imgur and attach it here. Totally impractical, but I'm an idiot when it comes to coding-related languages.

You mean microsoft word?
