Compute by hand or excel required information for the vertical curve in question $3.$

$1.$ The elevation and grade at station for each full station between the BVC and the EVC.

$2.$ Calculate the station and elevation of BVC$,$ PVI, CVC$,$ EVC and the Low or High Point for the vertical curves.

$3.$ Calculate the first and second differences for the vertical curves.

$4.$ Calculate the additional grades for each vertical curve.

$5.$ Calculate c and r for each vertical curves.
