Unlocking the Secrets of Right Triangle Trigonometry: From Basics to Real-World Applications

Right Triangle Trig Summary

Page 1:

  • Introduction to right triangle trigonometry.
  • Trigonometric ratios: sin(θ), cos(θ), tan(θ), csc(θ), sec(θ), cot(θ).
  • Mnemonic device: SOH CAH TOA.
  • These are all ratios, so infinitely many possible side combinations exist.

  • Examples to evaluate trig functions.
  • Special angles: 45°, 30°, 60°.
  • Function values for these angles are useful.

  • Continuation of special angles.
  • Cofunction identities.
  • Angles of elevation and depression.

  • Problem-solving using angles of elevation.
  • Applied examples: angle of elevation of the Sun.
