Trigonometric Functions
Standard Functions:
• sin(θ) = opposite / hypotenuse
• cos(θ) = adjacent / hypotenuse
• tan(θ) = opposite / adjacent = sin(θ) / cos(θ)
• sin(θ) = opposite / hypotenuse
• cos(θ) = adjacent / hypotenuse
• tan(θ) = opposite / adjacent = sin(θ) / cos(θ)
Reciprocal Functions:
• csc(θ) = 1 / sin(θ)
• sec(θ) = 1 / cos(θ)
• cot(θ) = 1 / tan(θ)
• csc(θ) = 1 / sin(θ)
• sec(θ) = 1 / cos(θ)
• cot(θ) = 1 / tan(θ)
Inverse Functions:
Return the angle whose trig function equals the input value.
Domain restrictions apply (e.g., -1 ≤ x ≤ 1 for arcsin/arccos).
