Its also used is for finding the exact values of angles that are outside the standard ones that you learn for methods. i.e

They will never tests,

Mr evans , wrote the book and is head of methods, used to be at my school  and told the teachers at our school they will never do it.

not even in exam 2?

Nope. To date, out of all the exams I've done, I have not seen one question that has asked for the application of the compound angle formula's.

Yeah I have done quite a few exams and I haven't come across it in a methods paper yet. However I know how to apply it as I do spec

You do NOT need to memorize them.

sweet as, also should we memorise the matrix representations of transformations?

yes, definitely

[TyErd]

ok thnx

[Jdog]

Matrices will definately be on exam one this time

what makes you so sure?

If you think about it, they already have given questions about conditional probability in past VCAA exam 1's. It's just its much easier to use a tree diagram for those questions than it is to use a matrix

i dunno, with those q's i always use matrices and visually think of the probability, ie if he had a beer on thursday, what would be the pr of having a beer on sunday, given that etc etc. Imo matrices are easier and quicker

There is a sample 2010 exam 1 for methods and it has matrices on it:

But then again, you could answer the question without using matrices lol.

I guess we should come to expect that different people have different ways of perceiving things
