Tabulate station elevations for an equal$-$tangent parabolic curve: $770-ft$ curve with grades of

$g1=-2\mathrm{.}75\%$ and $g2=-4\mathrm{.}5\%,V$ is at elevation of $550\mathrm{.}25ft.$ Station of BVC IS $31+23.$ Stakeout

the vertical curve at BVC$,$ EVC and full stations.

$*$Note: In your calculations, find your $"r($in $\%$ of stations$)"$ with two decimals. Also find

all layout table calculations with three decimals$*$
