# vvcosisin(_:_:_:)

Calculates the cosine and sine of each element in an array of double-precision values.

## Declaration

```swift
func vvcosisin(_: OpaquePointer, _: UnsafePointer<Double>, _: UnsafePointer<Int32>)
```

## Discussion

Discussion Parameters: This function calculates the complex number on the unit circle corresponding to the angle given by each element of a vector. The following code shows an example of using vvcosisin(_:_:_:). On return, for each array element in y, real is the cosine of x and imag is the sine of x.
