Exactly where is your difficulty?Find the length of the curve: .
We have: .
Therefore: . Got it?
I am having some trouble with finding the length of the curve
ln(secx), 0≤ X ≤π/4 (the last limit is pi over 4, the pi doesnt look right)
I am just not sure how to approach taking the derivative of this problem to later incorporate into the arc length forumla:
Any help would be great, and please include a description.
