Question: Tabulate station elevations ( stakeout at full stations ) for an equal - tangent parabolic curve with a 5 0 0 - f t curve,

Tabulate station elevations (stakeout at full stations) for an equal-tangent parabolic curve with a 500-ft curve, grades of g1=-3.00% and g2=-1.25%, VPI at station 38+00, and elevation 560.00ft. Check the table by second differences. Without calculations can you guess what is the minimum elevation on this curve and where is it located at?
