Trigonometry in Engineering and Design

Building with Trigonometry

Engineers and designers use trigonometry to create safe, sturdy, and beautiful structures. From bridges to roller coasters, angles and forces must be calculated precisely.

  • Trigonometry ensures beams are cut at the right angles.
  • It helps design ramps and roofs with the correct slopes.

Without trigonometry, our world wouldn't be so well built!

Examples

  • A roof designer uses trigonometry to calculate the correct angle for water drainage.

  • Bridge engineers use sine and cosine to determine the forces acting on suspension cables.
