These sections explain the job in plain language and set expectations for what the tool should do well.
A scientific calculator extends a basic calculator with functions used in math, science, and engineering, including trigonometry, logarithms, exponents, roots, and factorials. Type an expression such as sin(30) + 2^3 or tap the on-screen keypad, choose degrees or radians, and see the result update live. Under the hood the expression is broken into tokens and evaluated by a proper parser rather than eval, so input is handled safely and errors like mismatched parentheses or division by zero are reported clearly. Everything runs in your browser with no uploads.
Short answers for the questions people usually have before trying a utility like this.
Instead of running your input as code with eval, the calculator tokenizes it and evaluates it with a recursive-descent parser, so only valid math is computed and malformed input produces a clear error.
Yes. Use the angle mode selector, and the trig functions sin, cos, tan, and their inverses adjust automatically.
The calculator detects these cases and shows a friendly message such as Division by zero or a missing parenthesis error instead of returning a broken result.
