Hi Jack,What is lim_(n→∞) ∫_(-∞)^∞〖〖 x〗^n e^(-n|x|) dm 〗?
Find the limit and prove your answer.
I suggest you should learn some LaTeX before posting questions since the characters that you use makes it difficult to understand what your question is. We have a nice collection of threads that you can use to learn LaTeX.
Is this your integral?
