Find Exact Radian Solution OR to nearest 100th of a radian
sqrt(3) sec x = -2
You need to at least show an attempt here before anyone can help you. Look at a graph of sec(x).
well, would the first step be changing it to
cos x = - (sqrt 3)/2
For what angles is cosine = -(√3)/2 ?
This is where I get confused...
it's not ∏/6 right? because it's negative
so it could be the 5∏/6 ?
and is that the only answer?
Since sine and cosine are periodic with period [itex]2\pi[/itex], no that is not the only solution.
Oh, would the other solution be 7π/6 +2πn ?
