🧮

Scientific Calculator

Perform basic and trigonometric mathematical operations.

How to Use This Tool

  • 1Use numbers and standard operators (+, -, ×, ÷) to build mathematical expressions.
  • 2Click trigonometric functions (sin, cos, tan) or square root (√) to apply functions to display value.
  • 3Press = to evaluate equations, or C to reset input.

How the Scientific Calculator Works

Use the calculator keypad to enter arithmetic expressions and use the available trigonometric and square-root functions. Trigonometric functions use degrees.

Formula

Calculation formula Basic operations: addition (+), subtraction (−), multiplication (×), and division (÷). Square root = √x. Trigonometric functions calculate sin(x), cos(x), and tan(x) using degrees.

Instructions

  1. Enter numbers and operators using the keypad.
  2. Use parentheses to control the order of calculations.
  3. Use sin, cos, tan, or √ for supported scientific operations.
  4. Press = to calculate or C to clear the display.
