I have a problem as follows:
cos((π/3) - X)
I then used the addition identity of cos(x-y) = cos x cos y + sin x sin y and got:
cos(π/3)*cosX + sin(π/3)*sinX
Then i used the unit circle to get
(1/2)*cosX + √(3)*sinX
And am now stuck. I'm supposed to solve for 'x' but i'm not sure how to continue.
-I'm supposed to use trig identities, of course.
