This diagram, the way it is drwan, is misleading!

Anything roated around an axis, or mirrored around an axes, or even on the line x=y) has its x, y values reveresed and the sign changes accordingly, depending on the quadrant it falls on!

op = 2. the left triangle is 30:60:90. angele o in this triangle is 30 degree. so angle o in the right triangle is 60 degree. so the right triangle formed on the x axis is also 30:60:90. so s = 1, t = sqrt3.

Thanks guys, trigonometry seems like an elegant way to do this... just brushed up on my sines and cosines (its been 5 years) :)

I think sm176811 is right, the diagram is misleading... threw me off.

in gmat, diagrams and figures are not drawn to scale. you cannot rely on your eyes.
