Here's one approach:
In the figure above, points P and Q lie on the circle with center O. What is the value of S?
a) 1/2
b) 1
c) √2
d) √3
e) (√2)/2
So, s = 1
Answer: B
Cheers,
Brent

Alternate approach:
If point (a, b) is rotated about the origin 90 degrees clockwise, the coordinates of the resulting point are (b, -a).
In the problem above, (-√3, 1) is rotated about the origin 90 degrees clockwise to yield (s, t).
Thus, (s, t) = (1, √3).
The correct answer is B.
