This tool produces comprehensive trigonometric tables for any angle range with configurable step sizes. It supports both degree and radian modes and renders all six primary trigonometric functions, including reciprocals. The results help you compare function values across angles, spot periodicity (e.g., sin and cos with 2π or 360° periods), and observe symmetry such as sin(−θ) = −sin(θ) and cos(−θ) = cos(θ).
Use it to prepare study sheets, verify homework, or generate reference data for spreadsheets and programming tasks. You can choose coarse steps (like 30°) to memorize special angles, or fine steps (like 1°) to inspect smooth trends. Precision control (0–10 decimals) keeps the output readable while still being numerically informative for engineering or coding workflows.
Angles are sampled at uniform intervals from start to end (inclusive). Where functions are undefined (e.g., tan at odd multiples of 90° in degree mode), the tool shows the infinity symbol to avoid confusion. In radian mode, remember π ≈ 3.14159: common special angles include π/6, π/4, π/3, and π/2. The reciprocal identities cot = 1/tan, sec = 1/cos, and csc = 1/sin are applied consistently across the table.
Subjects Covered:
- Trigonometric function evaluation in degrees and radians
- Sampling step, range selection, and precision control
- Reciprocal identities: cot = 1/tan, sec = 1/cos, csc = 1/sin
- Data export and tabular presentation
