Review excel formulas for construction data processing

My project entails reviewing various Excel formulas to handle advanced calculations to interpret coordinates from our total station. It's about slope changes, north/south distances, east/west variations, etc. I have all formulas set up and data to test them against, I just need someone to review and confirm we're using the correct calculations. It's only about reviewing 3-4 formulas

If you think you have the skill to take on this task, please let me know. Thank you!
