2cos(t)=sqrt(3)
How to get all posible answers?(4posible answers)
When to use +2npi or +pi after the answers?
+130540 2cos(t)=sqrt(3) divide both sides by 2
cos(t) = sqt(3)/2 and this occurs at pi/6 + n(2pi) and at (11/6)pi + n(2pi) where n is an integer
Notice that using n(pi) after the answers would not be correct.....for instance, if n =1
pi/6 + 1*pi = 7pi/6 .....but the cosine does not = sqrt(3)/2 at 7pi/6
