About the Math Evaluator
The Math Evaluator is a powerful online calculator that evaluates complex mathematical expressions in real-time. Unlike basic calculators, it supports a wide range of mathematical functions including trigonometric functions (sin, cos, tan), logarithmic functions (log, log10), power functions (pow), square roots (sqrt), absolute values (abs), and standard arithmetic. It uses JavaScript's built-in Math library to provide accurate results for engineering, scientific, and everyday calculations.
How to Use the Math Evaluator
Type an Expression: Enter any mathematical expression using standard operators (+, -, *, /) and Math functions.
Use Quick Buttons: Click the function buttons (sin, cos, sqrt, etc.) to insert them at the cursor position.
View Results: Results update instantly as you type. Errors are displayed if the expression is invalid.
Check History: Previous calculations are saved in the history panel. Click any entry to re-evaluate it.

Frequently Asked Questions
The evaluator supports sin, cos, tan, asin, acos, atan, sqrt, cbrt, log (natural), log10 (base-10), log2, pow, abs, ceil, floor, round, min, max, and random. Constants PI and E (Euler's number) are also available.
Trigonometric functions (sin, cos, tan) use radians by default. To use degrees, multiply by PI/180, e.g., sin(45*PI/180) for sin(45°). Alternatively, use the degree-to-radian conversion: sin(45*3.14159/180).
The evaluator can handle expressions up to the JavaScript engine's recursion and memory limits. For practical purposes, expressions with hundreds of nested function calls work fine. Extremely deep nesting may cause stack overflow errors.
No, all calculations are performed locally in your browser. The calculation history is stored only in your browser's memory and is cleared when you close the page. No data is ever sent to any server.
