AROC and IROC were both reviewed today. If you do not recall how to do AROC and/or IROC please refer back to the previous posts. In general, when doing AROC/IROC questions, please keep in mind the following:
1. Your concluding statement should include/explain:
a) what the number you calculated means
b) the proper units (ie: m/min)
c) when this rate of change takes place (ie: at 22mins)
If you have a graphing calculator, you can also use the dy/dx function to help you calculate the rate of change.
And please remember to set your calculator to radian or degree- depending on the question you're asked to do.
