Question

How do you find the constant c when you've already found the taylor series expansion of lnx about c=2.

Answer 1

c=2? I don't understand the question

Answer 2

Is it the case you've expanded about the point c and you have something like,
\[\sum_{}{}=\ln c + \frac{x-c}{c}-\frac{(x-c)^2}{2c^2}+...\]and you want to know what to do now?

Answer 3

i.e. with ln(c)?
