Question:

Write a MathCad solution to compute the ellipsoid radii at a point. Use the defining parameters for the GRS80 ellipsoid - a and f - in table 19.1. Program Equation 19.2a, page 531, in the text to compute the ellipsoid eccentricity, and Equations 19.4 and 19.5, page 535, in the text to compute the radii - M and N. Show the results for the radius of the meridian and the radius of the prime vertical at

N. Lat. = 00° 00' 00.00", W. Long. = 86° 54' 54.00" (At Equator)

N. Lat. = 40° 25' 47.00", W. Long. = 86° 54' 54.00" (Purdue CE)

N. Lat. = 90° 00' 00.00", W. Long. = 86° 54' 54.00" (At Pole)
