Key Math Functions Guide

  • Trigonometric Functions

    Use sin, cos, tan buttons to calculate sine, cosine, and tangent of angles. Used in architecture, design, wave analysis, etc.

  • Logarithmic Functions

    log calculates common logarithm (base 10), and ln calculates natural logarithm (base e). Used in data analysis and acoustics (decibels).

  • Powers & Roots

    Provides , , and (root) functions. Essential for area calculation and standard deviation in statistics.

How to Use

  1. Enter Formula: Input numbers using buttons on the screen or your keyboard.
  2. Use Functions: Press function buttons like sin, cos, log first, then enter numbers, or use parentheses for complex formulas.
    Ex: sin(30) + log(100)
  3. Get Result: Press = button to display the calculation result.
  4. Reset: Press AC (All Clear) to clear all inputs. CE clears only the recent input.

FAQ

Q. Does it use Degrees or Radians?

Currently, this calculator basically uses Degrees. Radian conversion feature will be added soon.

Q. Is calculation history saved?

For security, history is cleared when you close the browser or refresh. We recommend noting down important results.

Q. Can I type with keyboard?

Yes, you can directly input numbers and operators (+, -, *, /) using your keyboard. Press Enter to calculate.
