Why can't countries like China and the US work together when it comes to space travel? How do we expect human-kind to advance and make great new discoveries if we can't all work together towards common goals?

I have just found this web site and was wondering IF there was some way to Subtract points from those idiots who gave frivilous and meaningless answers. If there was, it would sure cut down on all the crap you have to scroll thru to see a Real answer.

If I (n) = Integral (limits pi/2 and 0) e^2x * Sin^n (x) dx

how do i show 2*I (n) = e^pi - n* Intergal (same limits) e^2x * Sin^(n-1) (x) cos (x) dx

Hence, prove

(4+n^2) I (n) = 2e^pi + n(n-1) * Intergrel(version n-2)

I can't quite get there although I have come close. Should I use reduction forumla method first or should i follow the intergration by parts first?

Any help will be appreciated!

I am trying to statistically normalize a behavioral dataset so that variables from different participants have the same minimum and maximum point. i.e. responces from different participants can have the same minimum and maximum variable. I tried logarithms but they dont work with negative values. Normalization such as standard deviation does not work either. What is the formula for my problem how can I do that?
