Scientific Calculator

Unlock advanced mathematical computations with our online Scientific Calculator. Designed to mimic the functionality of a traditional handheld scientific calculator, this tool allows you to perform basic arithmetic, complex scientific functions, and work with mathematical constants directly in your browser.

What is a Scientific Calculator?

A scientific calculator is an electronic calculator, usually handheld, that can perform complex mathematical operations beyond basic arithmetic. These include trigonometric functions (sine, cosine, tangent), logarithmic functions (log, natural log), exponential functions, square roots, and working with mathematical constants like Pi (π) and Euler's number (e).

Key Features of This Calculator

  • Basic Arithmetic: Addition, subtraction, multiplication, division, and percentage.
  • Exponents: Calculate powers (xy) using the '^' button.
  • Roots: Find the square root of a number using 'sqrt()'.
  • Trigonometry: Compute sine, cosine, and tangent for angles (assumes degrees for input).
  • Logarithms: Natural logarithm (ln) and base-10 logarithm (log).
  • Constants: Use mathematical constants Pi (π) and Euler's number (e).
  • Parentheses: Group operations to control the order of evaluation.
  • Absolute Value: Find the absolute value of a number using 'abs()'.

How to Use This Scientific Calculator

Using the calculator is straightforward:

  1. Input Numbers and Operators: Click the number buttons (0-9) and operator buttons (+, -, *, /, %) to build your expression.
  2. Use Scientific Functions: For functions like sine, cosine, log, etc., click the corresponding button (e.g., 'sin('). This will add the function name followed by an opening parenthesis to the display. You then need to input the argument for the function and close the parenthesis.
  3. Constants: Click 'PI' or 'E' to insert these mathematical constants into your expression.
  4. Exponents: Use the 'xy' button (represented as '^') for powers. For example, to calculate 2 to the power of 3, type '2^3'.
  5. Parentheses: Use '(' and ')' to define the order of operations, just like in standard math.
  6. Calculate: Press the '=' button to evaluate the expression and display the result.
  7. Clear: Use 'C' to clear the entire display and start a new calculation.
  8. Backspace: Use '⌫' to delete the last character entered.
