# Atn Function

Trigonomeetriline funktsioon, mis tagastab arvavaldise arkustangensi. Tagastatav vĂ¤Ă¤rtus on vahemikus -Ď€/2 kuni +Ď€/2.

The arctangent is the inverse of the tangent function. The Atn Function returns the angle "Alpha", expressed in radians, using the tangent of this angle. The function can also return the angle "Alpha" by comparing the ratio of the length of the side that is opposite of the angle to the length of the side that is adjacent to the angle in a right-angled triangle.

Atn(side opposite the angle/side adjacent to angle)= Alpha

### SĂĽntaks:

Double

### Parameetrid:

Number: Any numerical expression that represents the ratio of two sides of a right triangle. The Atn function returns the corresponding angle in radians (arctangent).

Pi is here the fixed circle constant with the rounded value 3.14159. Pi is a Basic mathematical constant.
