    tf.math.atan2(
        y, x, name=None
    )

This is the angle \\( \\theta \\in \[-\\pi, \\pi\] \\) such that
\\\[ x = r \\cos(\\theta) \\\]
and
\\\[ y = r \\sin(\\theta) \\\]
where \\(r = \\sqrt{x\^2 + y\^2} \\).

#### For example:

    x = [1., 1.]
    y = [1., -1.]
    print((tf.math.atan2(y,x) * (180 / np.pi)).numpy())
    [ 45. -45.]
