I tried to evaluate t the limit of a procedure using the command limit('phi1(x)', x = infinity), here phi1(x) is a procedure and x must be integers. I got an error from maple "Error, (in phi1) final value in for loop must be numeric or character". x must be integers in this case. I dont know how to fix it. Is there an option in the command 'limit' thats related to this issue? Thanks for your help!
