easy mah
let the points be Xn, Yn lor then find for the, find the eqns for
the tangent lines and find the x and y intersects in terms of the
Xn s. then use the distance to find eqns to solve lor.
or a simpler way will be if i am not wrong the points must have the
same y value and same absolute x value. so all you need to do is to
find the point where the angle the tangent line makes 60 or 120
degrees lor.( thats when the gradient = sqrt3)
