z=f(x,y)= (cos y) - (cos x)
u are at the origin and want to hike to point (4pie,0,0). U want to get to 4pie,0,0 by hiking a route that alway keeps you at the same elevation. what is the length of this route?
I ploted the graph and I already know the route that will keep me at the same elevation from origin to 4pie,0,0 but how do I find the length of that route??
As for the second part
Your second route always moves along the gradient. Determine such a route of minimal lenght, assuming you start hiking in the positive x direction. What is the length? If you cannot find and exact answer, then determine an upper bound and a lower bound bbetween which the actual length must lie.
I have no clue on doing the second part.
I need some serious help because this will determine my final grade so be clear and help me as much as u can. Thanks
