Inverse trigonometric functions - a mathematical function is the inverse trigonometric functions.

Title inverse trigonometric function is formed from the name of the trigonometric functions using the prefix «arc-» (from the Latin. Arc - an arc). This is because the geometric meaning of the inverse trigonometric function equal to the arc of the unit circle (or the angle subtending the arc), which relies on a given segment.

Inverse trigonometric functions are used to calculate the angles of a triangle if you know him.

Here are six basic inverse trigonometric functions:

1. arcsine (arcsin)
2. arccosine (arccos)
3. arctangent (arctg)
4. arccotangent (arccot)
5. arcsecant (arcsec(x) = arccos(1 / x))
6. arccosecant (arccsc(x) = arcsin(1 / x))
