@acer  thank you so much. its working.

@tomleslie yes it is working. Thank you so much !!!

@tomleslie  thank you for pointing out the typo error. But this mistake happens while copying the code in the website, not in the Maple software.

@vv  if theis expression is not convergent then also maple should able integrate and solution will look like" Undefine" or something like that..but I'm sure it is a convergent expression.

@tomleslie  Thank you!! i will follow your steps and get back to you. thank you!!
