2. Pythagorean Identities
- sin²θ + cos²θ = 1
- 1 + tan²θ = sec²θ
- 1 + cot²θ = csc²θ
3. Trigonometric Functions of Negative Angles
- sin(-θ) = -sinθ
- cos(-θ) = cosθ
- tan(-θ) = -tanθ
- csc(-θ) = -cscθ
- sec(-θ) = secθ
- cot(-θ) = -cotθ
4. Angle Sum and Difference Formulas
- sin(A + B) = sinAcosB + cosAsinB
- sin(A - B) = sinAcosB - cosAsinB
- cos(A + B) = cosAcosB - sinAsinB
- cos(A - B) = cosAcosB + sinAsinB
- tan(A + B) = (tanA + tanB) / (1 - tanA tanB)
- tan(A - B) = (tanA - tanB) / (1 + tanA tanB)
