comment How to solve definite integral involving exponential function
You mention that you want to perform some analysis on f. Most of the time, this can be done without getting a "closed form". So, your real question is about properties of this function, not about the closed form.

comment Probability of each edge in K-clique
My point is not so much that assisting a cheating student is unethical, but that the questions that are not on the level appropriate for MathOverflow (as defined in Help Center) should not be encouraged by being answered.

I vote down as MO should not be a place where a solutions to standard exercises are given.

This is not a research-level question, being a standard exercise. I vote to close as being off-topic for MO.

comment Sylow-subgroups of the group of units of a finite field
Sometimes (p-1)/2 is a prime, sometimes it is not. Conjecturally, the former happens infinitely often. There is no universal answer. Probably you should explain what you are looking for, and why, so that we can help. Are you interested in a worst case? Then define "worst". Are you interested in average-case behavior, then what are you averaging over, p or n, etc.
