Suppose that you stand at the point (4,5,0) and look in the direction of a point that is not visible because it is behind the ball. You will then be looking at a point on the sphere.

If (−3,−4,1) is not visible from (4,5,0) find the point on the sphere at which you are looking if you look in the direction of (−3,−4,1). Otherwise, find the point on the sphere at which you look if you are looking in the direction of (−3,−4,0).
Point (x,y,z)=

Suppose you are looking at a field [m[x,y],n[x,y]] which has one singualrity at a point P and no other singularities. While studying the singulairty, you center a circle of radius r on the point P and no other singularites. While studying the singularity, you center a circle of radius r on the point P and parameterize this circle in the counter-clockwise direction as Cr;{x[t],y[t]}. You calculate (integralCr) -n[x[t],y[t]]x'[t] + m[x[t], y[t]]y'[t]dt and find that it is equal to -1 +...
