I like toast
OpenStudy (zehanz):
Try to factor: you can factor out cos x
OpenStudy (zehanz):
cos x(1+2sin x)=0

ZeHanz = Afganistan PIMP
OpenStudy (zehanz):
So cos x = 0 or 1+2sin x = 0
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
don't lie . . .

@Swaazy look i asked for help not someone to annoy me
OpenStudy (anonymous):
and here comes your mother with those two little guys.
Punched me in the belly and stepped on my feet, wauh slammed the bit* on the hard concrete
OpenStudy (zehanz):
cos x = 0 or sin x = -½
Now try to remember what values of x will give cos x = 0 or sin x = -½...
OpenStudy (anonymous):
The pimp was strong, the bit*h was gone, something was wrong I said what is going on?
OpenStudy (anonymous):
@Swaazy you are now block thanks have a nice life

@Shawna17: can you look up these values in a table?
OpenStudy (anonymous):
how would I do that do you have a link?
OpenStudy (zehanz):
You could use this one, see image
OpenStudy (anonymous):
my choices are
A. 0, pi/2, 7pi/6, 3pi/2
B. pi/2, 7pi/6, 3pi/2,11pi/6
C 7pi/6, 11pi/6, 2pi
D. 7pi/6, 11pi/6

OpenStudy (zehanz):
cos x = 0 gives pi/2 and 3pi/2
sin x = -½ gives 7pi/6 and 11pi/6
OpenStudy (anonymous):
so it's B
OpenStudy (zehanz):
Yup!
