Computes the two-argument arctangent of symbolic expressions.
Syntax
sym.atan2(y, x)
Description
Computes the two-argument arctangent of symbolic expressions. Returns the angle θ in (-π, π] such that (cos(θ), sin(θ)) is proportional to (x, y). This is the angle of the vector (x, y) from the positive x-axis, correctly handling all four quadrants.
Parameters
| Name | Description |
|---|---|
| y | - The y-coordinate (opposite side / numerator in y/x). |
| x | - The x-coordinate (adjacent side / denominator in y/x). |
