Some Thoughts re(2): solution | Comment 6 of 11 |
(In reply to re: solution by Charlie)

I agree with your comment, but to show how insignificant
the value of  d is, I needed to use some kind of calculator.

In my previous version I've solved    p&p , for c=.125 and c=.12  - was ok in both cases.

So, following your remark, I re-edited my post and now  I think that it gets your approval.

Please comment.
