Scientific Calculator Online Free
TheScientific Calculator is a versatile, user-friendly tool for performing basic and advanced mathematical operations, including arithmetic, trigonometry (sin, cos, tan), logarithms (log, ln), exponentials (e^x, 10^x), factorials, and more. Users input expressions via a virtual keyboard or physical keyboard, toggle between radians (RAD) and degrees (DEG) modes, and view results with a history of calculations.The tool includes educational explanations of mathematical functions, making it ideal for students, engineers, scientists, and professionals worldwide.
Calculation Process
1. Select Mode:
Choose between RAD (radians) or DEG (degrees). Default is RAD. Displayed at the top-left.
2. Enter Expression:
Use buttons or keyboard for:
Numbers & Symbols: 0–9, ., +, −, ×, ÷, ^, %, (, )
Functions: sin, cos, tan, asin, acos, atan, log, ln, √, e^x, 10^x, |x|, x!, 1/x
Constants: π, e
EXP: For scientific notation (e.g., 1e+2 = 100)
Example: sin(π/6) + 2^3
3. Validate Input:
Prevents invalid entries (e.g., double decimals, negative factorials).
Use Backspace to delete, C to clear all.
4. Calculate:
Press
=orEnter.Converts symbols/functions to JS equivalents (e.g., π → Math.PI, ^ → **).
Trig functions adjust for RAD/DEG mode.
5. Show Result:
Formats results (e.g., trims zeros, uses exponential form if needed).
Shows “Error” for invalid inputs.
6. History:
Saves past expressions with results.
Click “History” to view.
7. Reset:
C clears input/output.
Backspace removes the last character.
