Let ABCDE be a regular pentagon on the unit sphere S with each side
equal to s and each angle equal to 4pi/5. Find the exact value of
cos a. Noticed that as in Euclidean geometry a regular pentagon
called a spear can be inscribed in a spherical circle
The only ideas that can be used include: area ABC-RA2(A+B+C-Ipi), the Pythagorean theorem: Cos c-cos a cos b. Vectors-dot product cross product, sin A-sin a/sin c; coS A-COs a sin...
