A crest vertical curves joining a +3% and -4% grade is to be designed for 90 km/h. If the tangents intersect at station 3+400,00 at an elevation of 76,00 m, determine the stations and elevations of the BVC (beginning of the vertical curve) and EVC (end of the vertical curve). Also calculate the elevations of intermediate points on the curve at the whole stations every 40m.
