Computes both the sine and cosine of a specified value (**x**). You must specify **x** in pi radians, which use fewer FPGA resources than radians. To convert a radian value to pi radians, multiply the value by pi.

An input to this operation.

You must specify this input in pi radians, which use fewer resources than radians. To convert radians to pi radians, multiply the radian value by pi.

Boolean value that describes whether the next data point has arrived for processing. Wire the **output valid** output of an upstream node to this input to transfer data from the upstream node to this node.

True | The next data point has arrived for processing. |

False | The next data point has not arrived for processing. |

Boolean value that specifies whether downstream nodes are ready for this node to return a new value.

Use **Feedback Node** to wire **ready for input** of a downstream node to **ready for output** of the current node. If this input is False during a given cycle, **output valid** returns False during that cycle.

True | The downstream node is ready for the next data point. |

False | The downstream node is not ready for the next data point. |

**Default: **False

Result of the operation in pi radians, which uses fewer resources on the FPGA.

This output assumes the same numeric representation as
**x**. When
**x** is of the form
**x** = a + b
*i*, that is, when
**x** is complex, the following equation defines
**sin**:

$\mathrm{sin}(x)=\mathrm{sin}(a)*\mathrm{cosh}(b)+i(\mathrm{cos}(a)*\mathrm{sinh}(b))$

**x** is of the form

*i*, that is, when
**x** is complex, the following equation defines
**cos**:

$\mathrm{cos}(x)=\mathrm{cos}(a)*\mathrm{cosh}(b)+i(-\mathrm{sin}(a)*\mathrm{sinh}(b))$

Boolean value that indicates whether this node computes a result that downstream nodes can use.

Wire this output to **input valid** of a downstream node to transfer data from the node to the downstream node.

True | Downstream nodes can use the result this node computes. |

False | This node returns an undefined value that downstream nodes cannot use. |
