Report the amount by which the `turtles`

' coordinates `xcor`

would change
if the `turtles`

were
to move forward the given distances with their current `headings`

.

```
dx(turtles, dist = 1)
# S4 method for agentMatrix,numeric
dx(turtles, dist = 1)
# S4 method for agentMatrix,missing
dx(turtles)
```

- turtles
`AgentMatrix`

object representing the moving`agents`

.- dist
Numeric. Vector of distances the

`turtles`

would have to move forward to compute the increment values. Must be of length 1 or of length`turtles`

. The default value is`dist = 1`

.

Numeric. Vector of length `turtles`

.

Report the sine of the `turtles`

' `heading`

multiplied by the `dist`

values. Heading 0 is north and angles are calculated in degrees in a
clockwise manner.
