Compute by hand or excel required information for the vertical curves in question $1$

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

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

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

$4.$ Calculate c and r for the vertical curve.

Equal Tangent Vertical Curve

$g1=-3\mathrm{.}50\%$

$g2=+0\mathrm{.}50\%$

PVI Station $=198+10\mathrm{.}00$

PVI Elevation $={378\mathrm{.}26}^{\text{'}}$

Length $of$ Curve $={500\mathrm{.}00}^{\text{'}}$
