"(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?
I 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
Not the answer you are looking for? Search for more explanations.
Oh 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.
please close the question
Uhm I still don't know if I get it right?
insert 0,1,2,3,4 to p
SO I was right then?
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
@IrishBoy123 This was already closed. :P
@mathway dont take this the wrong way but you're beautiful
@Zupari I don't think so, but thank you haha. You're beautiful, too!
