y= |3sin(x)|

Why is the period pie?

Just graph, 3 sin(x) out, and then reflect all of the components below the X axis up. It will look just like the maccas symbol,and you will see that the graph will start to repeat itself after intervals of pi.

So the period is when the graph repeats itself?

Yes.

Ie when the part of the graph comes around again.

Is there a difference between a Markov sequence and a Markov chain? Because Markov sequences appear in the non-CAS course under Binomial Distribution (At least they appear in the Essential MM Non-CAS book under that chapter).

Basically the same thing just without the matrix. The notation is the same.

You guys are telling me you got to do matices? Not fair! :(

What's the general solution for circular functions? If you mean just how to solve them, definitely

But the formula is long, do we have to memorise it?

depends which one, it's not really a general solution, it's just adding on the period to the respective answers where
