Best ResponseYou've already chosen the best response.0"(sin x)(cos x) " you can make this a double angle in sin or you can just go through and work out when either sinx= or cos x = 0, because the other is always 1 < < 1 do you have a preference?

Best ResponseYou've already chosen the best response.0I actually have a clue with this, but I just want to make sure I was correct. I made sin x=0 and cos x=0, so my answers are 0, pi/2,pi, 3pi/2

Best ResponseYou've already chosen the best response.0Oh yeah right. I was looking at my unit circle and I completely forgot to look at 360 (2pi) because it lies the same with 0 degree.

Best ResponseYou've already chosen the best response.0@mathway close *your* question when you are happy to close *your* question :p you point about 0 coinciding with 2 pi is well made but i'd say that the interval is 0 to 2 pi so it would be right to list 2 pi also; though it is your prerogative well done and thanks
