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...
