我想問可以點prove from the first step to the second step? 希望有心人可以幫幫我在明天前解到。謝謝。 I have been trying to integrate it to get rid of the summation but apparently it is not working. Hopefully, someone could please enlighten me.

I have re-uploaded the photo and twisted it with a cam scan program, which might be advantageous: to serve those who struggle to read my handwriting.

I advise you to ask this in a website called maths stack exchange. It's a website for people to ask maths question. There are much more people will help you.
p.s. Remember to tell what you have tried to solve the problem.
