why the solution is in limit approaches to form??? need to have a closed form expression. any help..????

Just a begineer in maple and dont know how to rectify this error.

any help..???

Need to evaluate above summation in maple. For simplicity infinity can be replaced by some constant say 1000.

The value of parameters used are:

alpha=73.11

beta=76.11

E=4.75

help....

Hello everyone.

need to know what is the difference between use of GAMMA and gamma in maple.

thanks.
