What is the difference between ∫ F∙dr and ∫ ∇f.dr, line integrals problem?
I'm trying to solve this problem
and I got the length by substituting dx by dy or the opposite, or I could use the parametric equation.
But the 2nd part is where I stop, please help me I have an exam in few hours :/ can someone explain in details how I would solve part B? Sorry for my english, not my native.
I have an exam tomorrow, please it is urgent.
