Question: How do I reduce a second order DE to a first order DE?

Hi

How can I obtain the following equation

(1/2)(dξ(φ))^2+V(φ)=0 

from

under  the condition φ=0 and dξφ=0 at ξ→±∞ by Maple and what is the form of V(φ)? (All symbols are constant with respect to φ except ni=ηexp⁡( φ)-γexp(-σφ)  .
