# tensorplay.functional.tan

Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.tan.html

```python
tensorplay.functional.tan(input, *, out=None) → Tensor
```

Returns a new tensor with the tangent of the elements of input.

$$\text{out}_{i} = \tan(\text{input}_{i})$$

Parameters:

input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

Keyword Arguments:

out ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), optional) – the output tensor.

Example:

```
>>> a = tensorplay.randn(4)
>>> a
tensor([-1.2027, -1.7687,  0.4412, -1.3856])
>>> tensorplay.tan(a)
tensor([-2.5930,  4.9859,  0.4722, -5.3366])
```
