[red and white kop!]

is it required to memorize trig ratios such as sin pi/3 = sqrt3 / 2?
will such ratios be given in examinations?

Actually yes you have to memorize them , but we have it on the wall of our class room .
But you can estimate it on the trigonometric circle.

Memorization is good - but it will be better if you knew how to derive those (from isoscales triangles). You have to do one or the other - preferably both.
