To compute the Rate of Change (ROC) in Erlang, you can use the following formula:

ROC = (P2 - P1) / (T2 - T1)

Where: ROC = Rate of Change P2 = New value P1 = Initial value T2 = New time T1 = Initial time

Here's a step-by-step guide to compute the ROC in Erlang:

- Determine the initial value (P1) and the initial time (T1) at which the value was measured.
- Determine the new value (P2) and the new time (T2) at which the value was measured.
- Subtract the initial value (P1) from the new value (P2).
- Subtract the initial time (T1) from the new time (T2).
- Divide the difference in values by the difference in time to get the Rate of Change (ROC).
- This will give you the rate at which the value is changing over time in Erlang.

For example, if the initial value (P1) is 10 Erlang, the new value (P2) is 20 Erlang, the initial time (T1) is 4 hours, and the new time (T2) is 8 hours.

ROC = (20 - 10) / (8 - 4) ROC = 10 / 4 ROC = 2.5 Erlang per hour

Therefore, the rate of change in Erlang is 2.5 Erlang per hour.
