tf.math.atan(
    x, name=None
)

The tf.math.atan operation returns the inverse of tf.math.tan, such that if y = tf.math.tan(x) then, x = tf.math.atan(y).

Note: The output of tf.math.atan will lie within the invertible range of tan, i.e (-pi/2, pi/2).

For example:

# Note: [1.047, 0.785] ~= [(pi/3), (pi/4)]
x = tf.constant([1.047, 0.785])
y = tf.math.tan(x) # [1.731261, 0.99920404]

tf.math.atan(y) # [1.047, 0.785] = x
