Domain and Range of Trigonometric Functions

Domain of Sine and Cosine
- Defined as all real numbers
- Expressed in interval notation: (-∞, ∞)
Range of Sine and Cosine
- Values limited to the interval: [-1, 1]
Domain of Tangent
- All real numbers except odd multiples of π/2 (90°)
- Set notation representation: {Θ | Θ ≠ (2n-1)π/2, n ∈ Z}
Range of Tangent
- Includes all real numbers
- Expressed in interval notation: (-∞, ∞)
Domain of Secant
- Like tangent, the domain consists of all real numbers except odd multiples of π/2 (90°)
- Set notation: {Θ | Θ ≠ (2n-1)π/2, n ∈ Z}
Range of Secant
- Values found in two intervals: y ≤ -1 or y ≥ 1
- Interval notation: (-∞, -1] U [1, ∞)
Domain of Cotangent
- Contains all real numbers except integer multiples of π (180°)
- Set notation: {Θ | Θ ≠ nπ, n ∈ Z}
Range of Cotangent
- All real numbers are included
- Interval representation: (-∞, ∞)
Domain of Cosecant
- Comprises all real numbers except integer multiples of π (180°)
- Set notation is: {Θ | Θ ≠ nπ, n ∈ Z}
Range of Cosecant
- Includes values y such that -1 ≤ y ≤ 1
- Interval notation: (-∞, -1] U [1, ∞)
