hi all,

are there any one who come accross such an expression:
ln(1+e^(a.x)). I need a serial representation (polynomial form) of it. It is going to be used in an optimizatiton problem based on x (x is not able to be ignored, whole expression is required). I would really appriciate if one gives a response soon...thanks,
