Dear Group,
I have a 2 coupled differential equations (first order) that need to be solved. They are of the form:
a[x]*a'[x] #138;-g[x]*(a[x]-b[x]), 
z'[x]#138;g[x]*(a[x]-b[x])-(b[x]-298]
a[0]== 298,b[0]== 298},{a,b},{x,0.0000000000001,1.0*0.000000001}], now 
g[x]==Integrate[f[x], {x, a[x], b[x]}]
I appreciate if you can help me solve them using Mathematica, i need to do this by Wed.
Mazin
