1a)Using Matlab or Excel to calculate the difference between M and N at every 10 degree of latitudes and plot a curve showing the difference. (add the Matlab or Excel codes and the plotted curve into word document) (M and N just a pronoun )

1b)Using Matlab or Excel to calculate the difference between geodetic and geocentric latitudes (geodetic-geocentric) at every 10 degree of latitudes and plot a curve showing the difference. (add the Matlab or Excel codes and the plotted curve into word document)

please answer all the question and show your steps or formula, thank you!

Relationship among those parameters - e2 = 2f-f2, 1-e2 = (1-1)2 - a/b = 1-f - a/b = (1-e)/1/2 - = WGS84 - a = 6378137 m - f =1/298.2572235634 approximation - a, b ~ 6400km - f 1:300, e20 e 2 ~1/150 -0.007 - Relationship among those parameters - e2 = 2f-f2, 1-e2 = (1-1)2 - a/b = 1-f - a/b = (1-e)/1/2 - = WGS84 - a = 6378137 m - f =1/298.2572235634 approximation - a, b ~ 6400km - f 1:300, e20 e 2 ~1/150 -0.007
