❓ Frequently Asked Questions

What is a Scientific Calculator?

A Scientific Calculator is an advanced calculator that supports mathematical functions beyond basic arithmetic. It includes trigonometric functions (sin, cos, tan), logarithms, square roots, factorials, and more. It's essential for students, engineers, and professionals.

What functions does this calculator support?

This calculator supports:

  • Basic: Addition, subtraction, multiplication, division, percentage
  • Trigonometric: sin, cos, tan, asin, acos, atan (in DEG or RAD mode)
  • Hyperbolic: sinh, cosh, tanh
  • Logarithmic: log (base 10), log₂ (base 2), ln (natural log)
  • Other: square root, square, cube, inverse (1/x), 10ˣ, factorial, absolute value

What is the difference between DEG and RAD?

DEG (degrees) mode calculates trigonometric functions using degrees (e.g., sin(90°) = 1). RAD (radians) mode uses radians (e.g., sin(π/2) = 1). You can switch between modes using the dropdown in the top-right corner.

Is this Scientific Calculator free?

Yes! Kognitrick Scientific Calculator is completely free to use. No registration, no hidden charges, no credit card required.

Can I use keyboard shortcuts?

Yes! The calculator supports keyboard input:

  • 0-9, . — Numbers and decimal point
  • +, -, *, / — Basic operations
  • Enter or = — Calculate result
  • Backspace — Delete last character
  • Escape or C — Clear all
  • (, ) — Parentheses
  • ^ — Power (exponent)
  • p — Pi (π)

Is my data safe? Do you store my calculations?

Absolutely! Your privacy is our top priority. All calculations are performed entirely in your browser using JavaScript. Your data never leaves your device — we do not store, track, or share any of your calculations.

Who can benefit from using a Scientific Calculator?

This tool is useful for:

  • Students studying math, physics, or engineering
  • Teachers and educators preparing lessons
  • Professionals needing quick calculations
  • Anyone who needs an advanced calculator
