Use results thoughtfully

Educational purpose

This calculator and its explanations are provided for general educational and informational use, not as professional engineering, scientific, medical, financial, or legal advice.

Approximation and exact forms

Decimal results use finite-precision arithmetic and are rounded for display. Exact symbolic forms are shown only when the input supports a defensible relationship such as 90° = π/2. A decimal input that has no justified symbolic form is not given an invented fraction.

Limits of automation

Check units, signs, parentheses, and precision. Independently verify results used in critical applications or decisions.

Advertising disclosure

Advertising is currently disabled. If advertising is enabled later, the owner must use genuine publisher details, provide required disclosures and consent controls, and keep ads visually separate from calculator actions.
