Scientific Calculator

Tool Overview

The Scientific Calculator with a crisp blue/orange theme. Everything runs locally in your browser, so trigonometry, logarithms, powers, factorials, and percentages stay private and fast without sending data to a server.

Key Features

🎯 Accurate Math Stack

• Sine, cosine, tangent plus inverse functions (asin, acos, atan)
• Degree/radian toggle so trig outputs match the angle system you expect
• Square, power, square root, reciprocal, percent, and factorial for quick transformations

🧮 Expression Friendly

• Type directly in the expression bar or tap the keypad buttons
• Parentheses, π, e, exponent ^, and backspace editing keep complex formulas tidy
• Inline validation catches incomplete or invalid expressions before you copy results

🧠 Memory & History

• MC/MR/M+/M- keys match a physical scientific calculator
• History preserves your recent calculations so you can re-run or tweak them quickly
• One-click copy for sharing outputs into docs, chats, or spreadsheets

Usage Examples

• Angles: sin(30) in degree mode or switch to radian mode for sin(π/6)
• Growth/decay: 1200 * (1.08^3) for three years of 8% growth
• Engineering math: log(12000) - ln(42) or sqrt(2)/2 for normalized vectors
• Percentages: 2450 * 18% for quick VAT or discount checks

Tips

• Switch angle mode before using sine, cosine, or tangent so the results match your expected units.
• Percent converts the preceding number into a fraction (50% → 0.5) so you can chain percentage math.
• Factorial is limited to 0–170 to avoid overflow; larger inputs will be rejected for accuracy.
• Use the history panel when you need to revisit or copy earlier expressions without retyping.
