What is a scientific?

A scientific calculator handles more than basic arithmetic. Enter an expression using parentheses, powers, square roots, trigonometric functions and logarithms. Trigonometric functions use radians. Expressions are parsed locally; the calculator does not send calculations to a server.

Formula and calculation method

Supported operations include +, −, ×, ÷, powers, parentheses, sin, cos, tan, sqrt, log, ln and abs. Trigonometry uses radians.

The result is only as reliable as the inputs and assumptions. This tool is educational and does not replace professional financial, medical, legal or academic advice.
