Other answers:

\[\cos(x)=\frac{-2}{3}\] \[\cos(x)=\cos(x+2 \pi n)\] \[\text{ so we have } \cos(x+2 n \pi)=\frac{-2}{3}\]
Now take arccos of both sides
\[x+2 n \pi=arc \cos(-\frac{2}{3})\]
to solve for x subtract 2npi on both sides
@myin on this..i have to learn this for ACT, but how would u solve it exactly? what does cos mean?
|dw:1326937963668:dw|
ok.
and sin?
opp/hyp
opp stands for..........?
opposite
so opposite of hypotenuse?
/ means divided by
cos(x) = -2/3 Find the inverse of the cosine, make sure calculator is in degree mode. x = cos^-1(-2/3)
great that's one solution
