How do you do General Solutions?

[wildareal]

I usually get the two reference angles + or - period. eg sin(x)=1/2

x= TT/6, 5TT/6

then:

x=2nTT+-TT/6 and x=2TTn+-5TT/6

That's the way I do it too but if you look at TT's stickied thread, it shows you the more conceptual way of doing it.

Have you been taught general solutions at school or are you reading ahead? We were never taught it last year in 1/2...

theres just 3 formulas you rember they make a lot of sense as well, so you don't have to spend ages memorizing them,

you forgot the n element of Z

that lil error can cost you a mark =P

...I'm a bit confused.

Isn't the plus/minus sign included in the element of Z? (I use element of J however.)

Also, is it necessary to state that n is an element of Z? I don't do it in my outcomes (and my teacher doesn't either ).

Z is an integer, and indicated ...-2,-1,0,1,2...
Typically books / VCAA/ Trial Exams solutions have n as an element of Z.

Yer most use Z, some use N.

You DO need to specify what is. If you don't, then what are the examiner's meant to do? Assume you know what you are doing?

Also, you don't need , because Z already covers negatives.
