Computes the trignometric inverse sine of x element-wise.

    x, name=None

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

Note: The output of tf.math.asin will lie within the invertible range of sine, 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.sin(x) # [0.8659266, 0.7068252]

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


  • x: A Tensor. Must be one of the following types: bfloat16, half, float32, float64, int32, int64, complex64, complex128.
  • name: A name for the operation (optional).


A Tensor. Has the same type as x.
