Oh, god!! I found my problem... I was using the inverses incorrectly -- in
Advanced Calculus
and I can't even do algebra correctly. To make a long story short, in the
second functions I was putting the x in the denominator when it needs to be
in the numerator...
But! Your post is not in vain, D

Hi Jacob,

Ok, I think I see why you're using this, but you have to be aware that the
decimal module itself is susceptible to imprecision:

At the risk of being blindingly obvious ---
ft[0] is lambda x:381*x/1250
yd[1] is lambda x:1250/(1143*
Okay, not a very descriptive subject, but here goes...
This is the code
