Solve the equation on the interval [0, 2π). cos x + 2 cos x sin x = 0

OpenStudy (anonymous):

OpenStudy (anonymous):

ok then what?

OpenStudy (anonymous):

thats the answer

OpenStudy (zehanz):

You should explain a little...

OpenStudy (zehanz):

(@Swaazy )

OpenStudy (anonymous):

naaaaah

OpenStudy (anonymous):

I like toast

OpenStudy (zehanz):

Try to factor: you can factor out cos x

OpenStudy (zehanz):

cos x(1+2sin x)=0

OpenStudy (anonymous):

quit trippin . . .

OpenStudy (anonymous):

ZeHanz = Afganistan PIMP

OpenStudy (zehanz):

So cos x = 0 or 1+2sin x = 0

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

don't lie . . .

OpenStudy (anonymous):

dry your eye

OpenStudy (anonymous):

@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

OpenStudy (anonymous):

yo

OpenStudy (zehanz):

@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!
