Study Notes
Trigonometric Identities
- If tan(θ) = 13/5, then we can find cos(θ) using the trigonometric identity: cos(θ) = 1 / √(1 + tan²(θ))
- Given tan(α) = 7/24, we can use the same identity to find cos(α)
- Similarly, if tan(β) = 3/4, we can find cos(β) using the same trigonometric identity
Key Formulas
- cos(θ) = 1 / √(1 + tan²(θ))
