Scientific Calculator offers buttons for sin, cos, tan, log, ln, sqrt, pow, and parentheses. Expressions are sanitized with a strict whitelist before a Function-based Math evaluation, not raw eval on arbitrary input.

FAQ
Is eval used on raw input?
No. Input is whitelisted and mapped to Math helpers before Function construction.
Radians or degrees?
Trig functions use degrees in this tool.
Extra notes
Scientific Calculator runs entirely in your browser so drafts and secrets never need to leave your device for processing. Keep a backup of long outputs in your own notes if you rely on them for production servers or live events. Accessibility friendly labels come from the module UI strings, and the layout follows the shared BeeForge .bf-tool shell for consistent spacing and buttons.
Support for developers, marketers, and everyday users is the same client-side model: open the page, configure options, copy or download, then paste into your workflow. BeeForge related links on the tool page point to companion utilities so you can move between related generators without hunting the hub.
When you share results with a teammate, paste into a ticket or gist rather than screenshotting alone, so the text remains searchable. If a browser privacy mode blocks clipboard helpers, select the output manually. Local processing also means the tool works offline after the page and scripts have loaded once.
Validate generated configs or hashes in a staging environment before production use. Prefer regenerating secrets after any accidental paste into chat. For teaching sessions, walk through one sample input end to end so students see how live updates and copy buttons behave together.
