Homework Statement
I need to find the approximation to:
[itex] X = m_N\>\bigg[\frac{m^2+\mu^2}{m_N^2 - (m^2+\mu^2)}\>\mathrm{ln} \bigg(\frac{m_N^2}{m^2+\mu^2} \bigg) - \frac{m^2-\mu^2}{m_N^2 - (m^2-\mu^2)}\>\mathrm{ln} \bigg(\frac{m_N^2}{m^2-\mu^2} \bigg) \bigg] [/itex]
for [itex] m^2 \gg \mu^2 [/itex].

N/A
The Attempt at a Solution
So obviously I can't just do [itex] m^2 \pm \mu^2 \approx m^2[/itex], otherwise X = 0, which makes me think that I need to expand the logs in some way...
Any help would be appreciated,
Thanks.
