Trigonometry

All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O.

Hipparchus, credited with compiling the first trigonometric table, is known as

In this right triangle: sin A = a/c; cos A = b/c; tan A = a/b.

Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
