The window "Surface X(u,v)" shows the sphere X(u,v) = (cos(u)cos(v), sin(u)cos(v), sin(v)), the loxodrome X(Y(t)) where X(u,v) is the sphere as just defined and Y(t) = (tan(beta)*(ln(t) – C), 2*arctan(t)), and the point X(Y(t

The window "Projection" displays the projection of the surface X(u,v) onto the tangent plane at X(u

It is possible to change C, beta, and t
