DQ and IRC

use the difference quotient, w/h=0.01 and estimate the instantaneous rate of change.

#10. P(r)=100(1+r)^2 where r=0.12

Can you show me how to set up to solve? I do not seem to grasp the idea of the letters and the corresponding #'s and where to place. :confused:

I don't have the actual answer for this problem, book only gives odds.

you want $\frac {P(r + h) - P(r)}h$ (usually for instantaneous rate of change, limits are involved, however, since they gave us constant values for r and h, i assume they don't want us to use that)

so you want: $\frac {P(0.12 + 0.01) - P(0.12)}{0.01}$

Since you figured out this one (well done (Star) ), I'm betting that by now you've figured out the answer to this latest one too.
