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.

Page 4:

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