Hi everyone,
i've this problem with Mathemtica:
i've got 2 expression depending on a and b:
expr1= 1.0019  1. Log[0.00190438  0.0249519 b] + (0.000040093 a
Log[0.152644/(0.152644 + 2 b)])/b
expr2=1.00004  1. Log[0.0000378969  0.0249519 b] + (0.000040093 a
Log[0.0030376/(0.0030376 + 2 b)])/b
I want to make the same this two expressions.
The problem is that if i try to solve this is one equation in two parameter:
a and b.
So i think to put inside some value of a and b so i make equal the two
expression less than 10^12 (for example)
I've to do a list of value:
b can vary beetwen 0.0015188 < b < 0.0015188 (the domain of logarithmic
function) and a must vary for example 2000 to 2000.
I can not find a waydo it. I try with list, and put the value inside, but
i've some problem.
if anyone can help I would be grateful...
Thank you!
