I'm pretty sure that's a CAS topic, somewhat.

It is somewhat covered in normal methods, but not using the summation notation.

Yeah, I do CAS...it's a note I wrote to myself ages ago in my revision book. Like "you got this wrong last time, do it again before the exam" kind of thing, and I can't remember where it's from.

Hey, on the topic of trig. functions can someone clarify how you determine what to add or subtract to the reference angle...?
i just seem to always get confused at that point..
e.g. solve 2sin(2x) = - root3 for x E [ - pie/2 , pie/2 ]
i get to sin(2x) = -root3/2.. then dont know what to add or subtract to pie/3
thanks.
