yeah n!, easyBy the way sorry , the post delete was not intentional here :P , just missed the exclamation
n! is the correct answer. quite simple.i guess you solved it using reduction formula.try using differentiation now.
I dont understand how to find an integral by differentiation.
so did you solve the previous question?
yes by "by parts" and reduction formula
