About Trigonometric Calculations
Trigonometric Functions
- • sin(θ): Opposite / Hypotenuse
- • cos(θ): Adjacent / Hypotenuse
- • tan(θ): Opposite / Adjacent
- • csc(θ): 1 / sin(θ)
- • sec(θ): 1 / cos(θ)
- • cot(θ): 1 / tan(θ)
Triangle Solving
- • Right Triangle: Use Pythagorean theorem and basic trig functions
- • Oblique Triangle: Use Law of Sines and Law of Cosines
- • Law of Sines: a/sin(A) = b/sin(B) = c/sin(C)
- • Law of Cosines: c² = a² + b² - 2ab·cos(C)
Angle Conversion
- • Degrees to Radians: multiply by π/180
- • Radians to Degrees: multiply by 180/π
- • Common Values: 30° = π/6, 45° = π/4, 60° = π/3, 90° = π/2
