Atn Function

Trigonometicna funkcija koja vraca arkustangent od jednog brojcanog izraza. Povratna vrijednost je u opsegu od -Pi/2 do +Pi/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

Double

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).

Da bi pretvorili radijane u stepene, pomnozi radijan sa Pi/180. Da bi pretvorili radijane u stepene, pomnozi radijane sa 180/Pi.

stepen=(radijan*180)/Pi

radijan=(stepen*Pi)/180

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