# Acosh {#openvino_docs_ops_arithmetic_Acosh_3}
|
|
|
|
**Versioned name**: *Acosh-3*
|
|
|
|
**Category**: *Arithmetic unary*
|
|
|
|
**Short description**: *Acosh* performs element-wise hyperbolic inverse cosine (arccosh) operation with given tensor.
|
|
|
|
**Detailed description**: Operation takes one input tensor and performs the element-wise hyperbolic inverse cosine operation on a given input tensor, based on the following mathematical formula:
|
|
|
|
\f[
|
|
a_{i} = acosh(a_{i})
|
|
\f]
|
|
|
|
**Attributes**: *Acosh* operation has no attributes.
|
|
|
|
**Inputs**
|
|
|
|
* **1**: A tensor of type *T* and arbitrary shape. **Required.**
|
|
|
|
**Outputs**
|
|
|
|
* **1**: The result of element-wise *Acosh* operation. A tensor of type *T* and the same shape as the input tensor.
|
|
|
|
**Types**
|
|
|
|
* *T*: any numeric type.
