A possible strategy to use is to find the sine, cosine, and tangent of the angles first. Then, find the other trigonometric functions easily using the reciprocals. How To Given the side lengths of a right triangle, evaluate the six trigonometric functions of one of the acute angles. If ...
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
Trigonometric identities were used to simplify expressions of trigonometric functions. Pascal's triangle is a triangular arrangement of binomial coefficients. Could it be possible to marry this two?Christopher WhiteChristopher Schwaner

Using right triangles and the concept of similarity, the trigonometric functions sine and cosine can be defined. These are functions of an angle which are investigated in trigonometry. A central theorem is the Pythagorean theorem, which states in any right triangle, the square of the length of ...
