Trig Identities – Trigonometry is an imperative part of mathematics which manages connections or relationship between the lengths and angles of triangles. It is a significant old idea and was first utilized in the third century BC. This part of science is connected with planar right-triangles (or the right-triangles in a two-dimensional plane with one angle equivalent to 90 degrees).

Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles.The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. In particular, 3rd-century astronomers first noted [citation needed] that the ratio of the lengths of ...

In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, antitrigonometric functions or cyclometric functions) are the inverse functions of the trigonometric functions (with suitably restricted domains).Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of ...

The Unit Circle: the "easy way" vs. the "hard way" Many students, frustrated and confused by the unit circle, choose to instead memorize the unit circle chart to get through it, and in the video(s) below (especially the last couple) I give you lots of tips to help do that. However, there are good reasons to take a more understanding-based approach.
