Sine, cosine, and tangent are the most widely used trigonometric functions. Their reciprocals, though used, are less common in modern mathematics. Trigonometric functions are also called circular functions. 6 trig functions The table below shows the six trigonometric function values for the specified angles in both degrees and radians.
Effortlessly find trigonometric function values (sin, cos, tan, cot) or solve for missing sides or angles in a right triangle using our remarkable tool crafted by experts.
Some exact trigonometric values are equivalent. For example, ( \frac{1}{√2}) = ( \frac{√2}{2}). The denominator has been rationalised. To be successful with exact trigonometric values, especially ...

Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd ...
