Trigonometric functions
Reading time: 1minTrigonometric functions started in the basic geometry of triangles, but now they comprise a complex field that's a central subject of calculus. Trigonometric functions have two modes of work: in degrees and in radians. See the Document settings section.

This is one of the many angles whose sine is the given number. It's the one in [-π/2,π/2]. |
 |
This is one of the many angles whose cosine is the given number. It's the one in [0,π]. |
 |
This is one of the many angles whose tangent is the given number. It's the one in (-π/2,π/2). |
You can use the Simplify action to force non-trivial simplifications over trigonometric expressions. Moreover, the Verify action can test for trigonometric identities.
