I need help with this problem:
given a cirlce on S^2 of radius p in the spherical metric, show that its area is 2pi(1-cos p)
given a cirlce on S^2 of radius p in the spherical metric, show that its area is 2pi(1-cos p)
Divide the circular region into ring-shaped slices of thickness ds, and integrate …given a cirlce on S^2 of radius p in the spherical metric, show that its area is 2pi(1-cos p)
Divide the circle into rings …I'm not sure I understand what you wrote.
