 February 26, 2009, 09:44 Integration #1 John Haynes Guest   Posts: n/a Can someone help me with the integration of this function with respect to x. Integral of [(e^(Xt))/((b+x)^(a+1))]. the limits of integration is zero to infinity. I couldn't use the integral sign using this messaging tool so if anyone try to help me, the integral sign should be included in the problem.

 February 26, 2009, 13:07 Re: Integration #4 John Haynes Guest   Posts: n/a I have just realised that the integration should not consist of the exponent term as I was trying to obtain the moment generating fucntion of a pdf. My main integrattion question is to obtain the integral of [(x^r)/(b+x)^(a+1)] in the limits of zero to infinity where a and b are constants.
