Requires:
- 2 Points A Method of finding the instant rate of change through looking at close points to your tangent point.
We find 2 points and get the AROC of the 2 points.
our points are: (4.99,0.01) , (5.01,-0.01)
‘IROC’ = (5.01 - 4.99) / (-0.01 - 0.01)
= (0.2)/(-0.2)
= -1
Works in this case, but this method will Never be accurate
