Introduction

This scientific calculator helps you evaluate advanced mathematical expressions directly in your browser. It supports trigonometric functions, logarithms, powers, roots, factorials, constants, memory operations, history, and both degree and radian angle modes.

How to Use

Enter an expression using the on-screen buttons or your keyboard. Choose DEG or RAD for trigonometric calculations, use parentheses for grouping, and press Enter or the equals button to calculate. You can reuse Ans, store values in memory, copy results, or select past results from history.

Features

  • Trigonometric functions with degree and radian modes
  • Logarithms, powers, roots, factorials, constants, and percent
  • Expression parser with parentheses and operator precedence
  • Memory buttons and recent calculation history
  • Keyboard input for fast calculations
  • Runs locally in the browser with no server upload

Frequently Asked Questions

Does this calculator use degrees or radians?

You can switch between DEG and RAD. Trigonometric functions use the selected angle mode, and inverse trigonometric functions return values in that mode.

Is percent supported?

Yes. Percent is a postfix operator. For example, 200*15% returns 30.

Are calculations sent to a server?

No. Expressions are parsed and calculated locally in your browser.
