The functions a basic calculator lacks
A basic calculator handles arithmetic; a scientific one adds the trigonometric, logarithmic and exponential functions that science, engineering and higher maths depend on. This calculator performs those advanced operations in your browser, so you have sine, cosine, logs, powers and roots without hunting for a physical device.
Getting the details right
The subtleties that catch people out are handled here: whether angles are in degrees or radians, which changes every trig result; the difference between the natural logarithm and log base ten; and operator precedence, so an expression evaluates the way mathematics intends rather than left to right. Getting these right is the difference between a correct answer and a plausible wrong one.
Always available, nothing installed
A scientific calculator in the browser is there whenever you need it, on any device, with nothing to install. It suits a quick calculation during study or work where reaching for a graphing calculator is overkill. The computation runs locally, so nothing you enter is sent anywhere.

Frequently Asked Questions
Does it work in degrees or radians?
It supports both, and choosing the right mode matters because every trigonometric result depends on it. A common error is computing a sine in the wrong angle mode.
What is the difference between log and ln?
Log usually means the base-ten logarithm; ln is the natural logarithm, base e. They give different values, and mixing them up is a frequent mistake.
Does it respect order of operations?
Yes. Expressions evaluate by mathematical precedence, so multiplication and powers are applied before addition, rather than strictly left to right.
What functions are included?
Trigonometric functions, logarithms, exponentials, powers and roots, alongside standard arithmetic.
Is anything uploaded?
No. The computation runs entirely in your browser.
