As a typical example of the results, here is a plot of relative errors when one of the endpoints is fixed at (lat, lon) = (45, 0): The contours are on a logarithmic (base 10) scale: the -6 contours show points where the relative error is 10^(-6); that is, one part per million (ppm). 2 How do you find the midpoint between two numbers? A. the x-coordinate of each halfway point is located halfway between the x-coordinate of a local maximum point and the x-coordinate of a local minimum point B. the x-coordinate of the halfway points are x=B/C and x= -B/C While planning a road trip usually begins with a starting location and a destination, the real work starts when it comes to figuring out where to stop, what to see, and how to get there.
