cos¶

paddle. cos ( x, name=None ) [source]

Cosine Operator. Computes cosine of x element-wise.

Input range is (-inf, inf) and output range is [-1,1].

\[out = cos(x)\]

Parameters

• x (Tensor) – Input of Cos operator, an N-D Tensor, with data type float32, float64 or float16.

• name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

Tensor. Output of Cos operator, a Tensor with shape same as input.

Examples

import paddle

x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
out = paddle.cos(x)
print(out)
# [0.92106099 0.98006658 0.99500417 0.95533649]
