# tensorplay.functional.sin

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

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

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

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

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([-0.5461,  0.1347, -2.7266, -0.2746])
>>> tensorplay.sin(a)
tensor([-0.5194,  0.1343, -0.4032, -0.2711])
```
