Right Spherical Triangles

Mathematrix_Formulas on Instagram: "the cosine rule for sides in spherical trigonometry allows us to determine unknown sides of a spherical triangle using known sides and angles. •Spherical version of the plane cosine law. •Accounts for the curvature of the sphere. •Gives accurate results for large-scale distances •When two sides and the included angle are known. •When solving oblique spherical triangles. •Common in navigation and astronomy problems.
