Study Notes

Trigonometry Formulas and Identities

If sinθ = 1/2, then the value of (3cosθ – 4cos³θ) is 0.

Trigonometric Ratios and Identities

tan40° = α, then (tan320° - tan310°) / (1 + tan320°.tan310°) = α² / (1 - α²).
cot²θ + cot⁴θ = 2, then 2sin⁴θ + sin²θ = 3.

Trigonometric Identities and Formulas

sin28°sin35°sin45°sec62°sec55° = -2.
sin(A + B) = sinAcosB + cosAsinB (used to find the value of sin28°sin35°sin45°sec62°sec55°).
tan(A - B) = (tanA - tanB) / (1 + tanAtanB) (used to find the value of tan40°).

Trigonometric Formulas and Inequalities

2sin4θ + sin²θ = 3, if cot²θ + cot⁴θ = 2.
|tanθ| ≥ |tan(45° - α)| (used to find the value of 2sin4θ + sin²θ).

Trigonometry Applications and Formulas

8sin30°sin60° - 4sin90° - sec45° = 2.
tan(45° - α) / (cot45° + sec45°) = tan(45° + α) (used to find the value of 8sin30°sin60° - 4sin90° - sec45°).

Trigonometric Identities and Formulas

(cosec²θ + cos²θ) = 2, if tanθ + 3cotθ - 2√3 = 0, 0° < θ < 90°.
sec²θ - tan²θ = 1 (used to find the value of cosec²θ + cos²θ).

Trigonometry Formulas and Identities

2sin⁴θ + sin²θ = 5, if 7sinθ + 4cosθ = 5 and θ lies in the first quadrant.
3secθ + tanθ = 5, if 7sinθ + 4cosθ = 5 and θ lies in the first quadrant.
