Topics in Heights and Distances

1

Basic Concepts and Definitions

  • Angle of elevation is formed when we look upward from horizontal line
  • Angle of depression is formed when we look downward from horizontal line
  • Line of sight is the straight line from observer's eye to the object
2

Problem-Solving Methodology

  • Step 1: Draw a clear diagram showing all given information
  • Step 2: Mark all right angles in the figure
  • Step 3: Label known quantities and angles
3

Types of Problems and Applications

  • Single triangle problems: Direct application of trigonometric ratios
  • Two observer problems: Same object viewed from different positions
  • Problems involving both elevation and depression angles
4

Important Trigonometric Values and Calculations

  • sin 30° = 1/2, cos 30° = √3/2, tan 30° = 1/√3
  • sin 45° = 1/√2, cos 45° = 1/√2, tan 45° = 1
  • sin 60° = √3/2, cos 60° = 1/2, tan 60° = √3
