Dear all,
I have difficulty in writing a macro for the following situation and
need help urgently on this. I would greatly appreciate any kind soul
outthere who is willing to help me out. :)

I have 2 funtions:

f = 1 + (1.4) * 2 / .005 * r
g = (1 / (1 - (1 / .005 * r))) ^ 2

I need to write a macro to incrementally calculate and display to 6
decimals, the first positive value of r such that f-g< precision where
precision will be a variable for the user to input.

Thank you.
