Scientific Calculator – Quick Cheat Sheet

• Supported functions: sin, cos, tan, asin, acos, atan, sqrt, ln, log, nthroot.
• Angle mode: Deg (default) or Rad. Trig/inverse trig respect this setting.
• Logs: ln(x) is natural log; log(x) is base-10.
• Constants: pi or π; e (Euler’s number).
• Ans: Use ans to reference the previous result.
• Exponent: Use ^ (e.g., 2^8).
• Roots: sqrt(x) or nthroot(x,n) for n-th root.
• Factorial: Only integer literals, e.g., 5!. (Not supported: (3+2)!.)
• Operators: +, -, ×/*, ÷//, %, parentheses, decimals, commas.
• Safety: Only the tokens above are accepted; anything else is rejected for security.
