See its because when there is no power lag, that is when the phase shift is 0 your other parameters shouldn't affect by the cos (phi). So when Phi=0 then cos (phi)=1. Therefore its much convenient to choose cosine rather than sine angles.

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
