Homework Statement
Part of an example of using reduction formula, I won't post the whole question as I get most of it, just at the very end, magical things happen with the working and things disappear, as they usually do with integration:
The definite integral goes from 0 to pi/4
=>[tex]\int[/tex] tan[tex]^{n-2}[/tex] x sec[tex]^{2}[/tex] x dx
=>tan[tex]^{n-1} x/n -1[/tex]
The Attempt at a Solution
My question is, what happened to the sec[tex]^{2}[/tex] x in the integration process?
I see the tan got integrated, but I can't figure out how sec disappears
