Atn function

Returns the tangent value of a value.

Atn(number)

The number argument can be any valid numeric expression.

Description

The Atn function calculates the ratio (number) ofThe two sides of a right-angled triangle and returns the Radian value of the corresponding angle. This ratio is the ratio of the length of the angle to the length of the adjacent edge. The range of results is from-PI/2 to PI/2 radians.

Radians are converted to angles by multiplying radians by pi/180. Conversely, the angle is converted to radians by multiplying the angle by the 180/PI.

The following example uses Atn to calculate the value of pi:

Atn(1) ' the calculated value.

Attention Atn is the inverse trigonometric functions of Tan, which returns the ratio of the angles to the sides of the right-angled triangle as a parameter. Do not confuse Atn with cotangent (the reciprocal (1/tangent)) function of the tangent.
