An equal-tangent crest vertical curve with a length L unknown, has an initial grade is G₁ = +2.5% and the final grade is G₂ = -1.0%. The highest point of the curve is at Xh = 800m, its elevation is yh = 1000m and its station is STA = 32 +000. Determine the stationing and elevation of the PVI, PVC, and PVT.
