Hi Professor Murray, for the last Additional problem question, I was wondering if when we integrate and distribute - integral (secx (sec^2x -1)dx), why didn't we get -integral sec^3xdx MINUS integral secxdx instead of -integral sec^3xdx PLUS integral secxdx ? I thought the negative sign distributes to both parts?

For Part one, why can't we say "let u= the even one"?

Prof. Murray,

When you took the integral of 1/8 Integral (1-cos 4x) dx did you forget to switch the signs? Should it have been 1/8(x + 1/4 sin (4x) + C ?

Thank you for the excellent lesson otherwise
