/2, /2] (that
is, -/2 < ATAN(a)< /2). The ATAN function returns the arc tangent of an expression
a. The range of ATAN is [-/2, /2] (that
is, -/2 < ATAN(a)< /2).
Format
ATAN(a)
Arguments
| a |
Any valid function expression. Number of arguments: 1 |
Examples
-10*ATAN(DY(42,33)/DX(42,33))
This function defines a torque. The value of the torque is the spring constant (10) multiplied by the angle between the line joining Markers 33 and 42 and the global x-axis as shown in the figure below.
