In right triangles, the trigonometric functions sine, cosine, and tangent represent the relationship between an angle and the ratio of two side lengths. Using angle A as an input, sine (A) is equal to the ratio of the opposite side length a to the hypotenuse h, cosine (A) is equal to...
The relationships between the angles and sides of spherical triangles are extensively used inastrometry. The three basic relationships are thesine formula: sinA/sina= sinB/sinb = sin C/sinc thecosine formula: cosa= cosbcosc+ sinbsinccosA
