You want to isolate for x right?

Yes

#

just $\cos^2(x)=1$, you can solve from there.

Yes, so what fish said is right. After that u want cos(x) = 1 or -1

#

Do you know how to do this

#

the question informed you that the value of x is between 2 pi and zero

#

so you just need to remember of the unit circle

#

got it

#

?

#

I got x = 0, pi and 2pi

#

is that correct?

#

or would it be pi

#

?
