QUESTION #57 Properties of Square and Diagonals
Let a be the length of a side of a square OABC with O being the origin. Its side OA makes an acute angle alpha with the positive x-axis and the equations of its diagonals are (sqrt3 + 1)x + (sqrt3 - 1)y = 0 quad textand (sqrt3 - 1)x - (sqrt3 + 1)y + 8sqrt3 = 0. Then a^2 is equal to

QUESTION #0 Rotation of Coordinate Axes / Distance from Origin
A line passing through the point P(a, 0) makes an acute angle alpha with the positive x-axis. Let this line be rotated about the point mathrmP through an angle fracalpha2 in the clock-wise direction. If in the new position, the slope of the line is 2 - sqrt3 and its distance from the origin is frac1sqrt2, then the value of 3mathrma^2tan^2alpha - 2sqrt3 is
