SolveNewton ( double a, double b, int &_IterationsCount ) : double	Numerically computes the intersection of a straight line with a strange curve we know the equation of... We're using the http://en.wikipedia.org/wiki/Newton's_method The computation is occurring in [ThetaH,ThetaD] space: ^ ThetaD | PI/2 +----------/-----+ ThetaH PI/2 We're looking for intersection point o given 2 values: the slope of the straight line and PhiD that guides the curvature of the strange curve C(y) The position of a point P on the line is given by P(x)=[x,slope.x] (we know the slope) we find o so that o = P(x) = C(y) So we can write: x = atan( tan(PI/2 - y) / cos(PhiD)) y = slope.x Replacing: x = atan( tan(PI/2 - slope.x) / cos(PhiD) ) Tanning: tan(x) = tan(PI/2 - slope.x) / cos(PhiD) Or: tan(x).tan(slope.x) = 1 / cos(PhiD) We know "slope" and "PhiD", we need solve to find x which is the ThetaH at which the intersection occurs...
