WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have the center at (2,3) and have a radius of 2 since 4 = 2^2. This means if you went a distance of 2 away from that center point you would be on the circle. Web3. Clairaut's relation for a great circle parametrized by t is r ( t) cos γ ( t) = Const where r is the distance to the z -axis and γ is the angle with the latitude. The implicit equation of …

Web1. Here is a much simpler proof. We know that the great circles of a sphere S 2 are geodesics. Let p and q be two points on S 2. Now find a plane that contains the center of the sphere, p and q. The intersection of the plane and the sphere is a great circle with p and q being points on the great circle. Hence, the geodesic joining p and q is ... WebAt f=0, we are at lat1,lon1.
