Land Surveyor's Guide

Common formulas and functions for land surveying:

• Area of a Triangle: A = 0.5 × base × height
• Area of a Rectangle: A = length × width
• Area of a Trapezoid: A = 0.5 × (a + b) × h, where a and b are parallel sides
• Pythagorean Theorem: c² = a² + b²
• Distance between two points: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
• Slope: m = (y₂ - y₁) / (x₂ - x₁)
• Volume of a Rectangular Prism: V = length × width × height
• Conversion: 1 acre = 43,560 square feet

Useful trigonometric functions:

• sin, cos, tan: For angle calculations
• arcsin, arccos, arctan: For inverse trigonometric calculations

Tips:

• Use the STO➔ button to store frequently used values
• Utilize the 2nd function to access additional features
• Practice unit conversions (e.g., feet to meters, acres to square meters)
