ATAN2
Returns the arc tangent of two expressions, each representing a numerical value. x1 and x2 themselves can be expressions.
Format
ATAN2(x1, x2)
Arguments
x1 | Any valid expression that evaluates to a real number. |
x2 | Any valid expression that evaluates to a real number. |
Example
The following function shows the arc tangent of the expression a/b where a is the x component of the distance between marker_2 and marker_1 and b is the y component of the distance between marker_2 and marker_1. The location of marker_1 and marker_2 is shown in the figure below.
Function | ATAN2 (DX(marker_2, marker_1, marker_2), DY(marker_2, marker_1, marker_2)) |
Result | 45 |
