cos(z)=cos(30∘)cos(47∘39′)+sin(30∘)sin(47∘39′)cos(124∘10′30′′)cosine z equals cosine open paren 30 raised to the composed with power close paren cosine open paren 47 raised to the composed with power 39 prime close paren plus sine open paren 30 raised to the composed with power close paren sine open paren 47 raised to the composed with power 39 prime close paren cosine open paren 124 raised to the composed with power 10 prime 30 double prime close paren

Then from equation (1) rearranged: $$\cos H = \frac\sin a - \sin \phi \sin \delta\cos \phi \cos \delta$$ spherical astronomy problems and solutions

Spherical astronomy is the branch of astronomy that deals with the celestial sphere—a projection of celestial objects onto an imaginary sphere centered on the observer. It is the foundation for determining positions, timekeeping, and navigation. spherical astronomy problems and solutions
