What is Scientific Calculator?
The Scientific Calculator brings trigonometry, logarithms, powers, roots, and constants into the browser with proper expression parsing and degree/radian switching. It covers the functions needed for physics, engineering, and exam-style problems without installing anything.
How to use Scientific Calculator
Enter an expression using the scientific keypad — sin, cos, tan, log, ln, powers, and roots.
Toggle between degrees and radians to match your problem's convention.
Build up nested expressions; the parser respects precedence and grouping.
Evaluate with equals or Enter and copy the result into your notes.
