2. Compute by hand and tabulate station elevations and the 1st and 2nd differences for an equal tangent parabolic (vertical) curve for the following data: A +3.50% (g1) grade meets a -4.00% (g2) grade at Station 12+65 (the PVI). The PVI Elevation = 300.00'. Length of Curve = 750'. Calculated elevations for full stations between the BVC and the EVC. Also, calculate the station and elevation of the curve for the PVI, BVC, EVC and the High Point. Place all the information in station order in a properly labeled and organized table using the exact format shown in the last slide of the Application of Vertical Curves Video. Show all elevations to 3 decimal places. Provide a page sized detailed and labeled sketch of the profile of the curve.

Electronic Spreadsheet

Tabular listing has many advantages ranging from time management to efficient scheduling of tasks. Electronic spreadsheets allow the user to tabulate and analyze data, using its easy-to-use interface. An electronic spreadsheet is a staple application used among accountants, management staff, and IT professionals. It is used in various sectors worldwide for data management. An electronic spreadsheet is a system and computer software that could be used to do numerical computations automatically. Spreadsheet application programs are often organized as a table with rows and columns. Each row and column intersect to form a cell, which may be used to store data. These data can take the form of a written label, a number, or a formula that combines information from other cells.
