Note: Trigonometric functions use Degrees by default. Switch to RAD for radians. All calculations run locally in your browser.

How to Use the Scientific Calculator

  1. Basic arithmetic — Use the number buttons and operators (+, −, ×, ÷) for standard calculations.
  2. Trigonometry — Press sin, cos, or tan for trigonometric functions. Use sin⁻¹, cos⁻¹, tan⁻¹ for inverse functions. Toggle between DEG and RAD modes.
  3. Logarithms & Powers — Use log, ln, log₂ for logarithms. Use x², x³, xʸ, √, ∛, and 10ˣ for powers and roots.
  4. Memory — Store values with MS, recall with MR, add/subtract with M+/M-, and clear with MC.
  5. Keyboard support — Use your keyboard for numbers, operators, parentheses, Enter for equals, Backspace for delete, and Escape for clear.

Why a Scientific Calculator Matters

Whether you're a student studying mathematics or physics, a professional in engineering or finance, or simply someone who needs to perform complex calculations, a scientific calculator is an essential tool. It goes beyond basic arithmetic to handle trigonometry, logarithms, exponential functions, and advanced operations.

This calculator is designed to be both powerful and accessible, with a clean interface, memory functions, calculation history, and full keyboard support. All calculations run locally in your browser — no data is ever sent to any server, ensuring complete privacy.

Key Features

  • Trigonometry — sin, cos, tan, and inverse functions with DEG/RAD mode toggle.
  • Logarithms — log (base 10), ln (natural), and log₂ (base 2).
  • Powers & Roots — x², x³, xʸ, √, ∛, 10ˣ, and eˣ.
  • Memory System — MC, MR, MS, M+, M- with visual memory indicator.
  • Advanced Functions — Factorial (n!), reciprocal (1/x), absolute value (|x|), and percentage.
  • Keyboard Support — Full keyboard controls for fast input.
  • Calculation History — Stores your last 10 calculations for easy reference.
  • 100% Private — All calculations happen locally in your browser.

Frequently Asked Questions

DEG (Degrees) mode interprets trigonometric function inputs in degrees (0-360°). RAD (Radians) mode uses radians (0-2π). Most high school math uses degrees, while calculus and advanced mathematics use radians. Use the toggle button to switch between modes.
MS stores the current display value to memory. MR recalls the stored value. M+ adds the current value to memory. M- subtracts the current value from memory. MC clears the memory. An "M" indicator appears when memory contains a value.
Use the xʸ button for any power (e.g., 2 xʸ 3 = 8). Use x² for squares, x³ for cubes, and 10ˣ for powers of 10. The eˣ button calculates Euler's number raised to a power.
The factorial function (n!) multiplies all positive integers from 1 to n. For example, 5! = 5×4×3×2×1 = 120. This calculator supports factorials up to 170! which is the maximum JavaScript can accurately compute.
Yes! You can use your keyboard: numbers (0-9), operators (+,-,*,/,^), parentheses (()), Enter or = for equals, Backspace for delete, and Escape for clear. The calculator works just like a physical calculator with keyboard support.
