I found a reference ( link below ) saying that the formula can be rewritten as α(v,u,w)=2arcsin(uv+uwv+w−−−−−−−−−−√)α(v,u,w)=2arcsin(uv+uwv+w) I cannot see the connection. I am referring to the paper"Collins, Charles R., and Kenneth Stephens...
Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.
