and the integral of (sec^4x)(tan x)dx

will substitution work for both of these problems

Why don't you just try substitution and see if it works?

and you dont get the same answer when you do it like that

if you just strait substitute you get sec^7x/5

and if you change a sec^2x to 1+tan you get tan^4x/2

I think, thats if im even doing it right
