Homework Statement
While I was in school I thought to see what a function whose derivative is always perpendicular to another functions derivative would look like, so for example for X^2 we have -ln(x)/2.
Homework Equations
Well all those integration tables I guess
The Attempt at a Solution
Obviously their product is -1, so if were looking for g(x),
g(x) = ∫(-1/f'(x))dx
However, I don't seem to be able to integrate this.
I need to have a ln(f'(x)), who's integral is f''(x)/f'(x), but dividing by f''(x) or try to subtract it just makes things much tougher. This isn't homework, but it would be very nice if I was to be helped. Please don't give solution, just clue.
Thanks, Bonaparte
