Supported functions are sqrt, sin, cos, tan, asin, acos, atan, ln, log, abs, and exp.
Constants are pi and e.
Degree mode converts trigonometric input angles to radians before calling real-number trig functions.
Inverse trigonometric functions return values in the selected angle mode.
Factorial accepts non-negative integers from 0 to 170.
Complex numbers, graphing, symbolic algebra, and implicit multiplication are out of scope.

Primary result: Result

Formula logic is kept in a pure calculator module with fixtures, source notes, and page-visible assumptions.

What the result means

Use Result as the headline answer for scientific. Evaluated real-number expression. Use the primary result for the scientific task, then check the secondary outputs for context. Use rounded result, angle mode, and parsed expression to explain why result moved when an input changed. Copy the result only after the inputs, assumptions, and source notes match your case. Check unit handling, rounding, included inputs, excluded inputs, and source version before treating the result as final.

ResultEvaluated real-number expression.

Rounded resultResult rounded to the requested number of decimal places.

Angle modeAngle unit used for trigonometric functions.

Parsed expressionTrimmed expression evaluated by the parser.

Use the result this way

Start with Result, then use supporting outputs only to explain the primary answer.
Verify expression, angle mode, and decimal places before copying the result.
Choose the mode or method first because it can change which formula is applied and stay within the documented minimum and maximum ranges.
Copy the result only after the inputs, assumptions, and source notes match your case.

Inputs

Enter expression, angle mode, and decimal places for number checks, homework, spreadsheet review, and quick comparisons. Before calculating, choose the mode or method first because it can change which formula is applied and stay within the documented minimum and maximum ranges. Expression: Use numbers, + - * / ^, parentheses, pi, e, sqrt, sin, cos, tan, ln, log, abs, exp, and!. Angle mode: Choose degrees or radians for trigonometric functions. Decimal places: Round the display result to 0-12 decimal places.

FAQ

How is result calculated here?

Evaluate real-number scientific expressions with powers, roots, logarithms, trigonometric functions, constants, and factorials. The first assumption to check is: Supported functions are sqrt, sin, cos, tan, asin, acos, atan, ln, log, abs, and exp.

What does Result mean for scientific?

Use the primary result for the scientific task, then check the secondary outputs for context. Secondary values such as rounded result, angle mode, and parsed expression are there to explain the primary answer, not to replace it.

What should I enter for Expression?

Use numbers, + - * / ^, parentheses, pi, e, sqrt, sin, cos, tan, ln, log, abs, exp, and!. Choose the mode or method first because it can change which formula is applied and stay within the documented minimum and maximum ranges.

How does Angle mode change result?

Choose degrees or radians for trigonometric functions. Changing it can alter result because the formula uses the submitted inputs together. Also compare unit handling, rounding, included inputs, excluded inputs, and source version.

Why does the scientific example show 1 for result?

The default inputs produce 1 for result. Treat that as a format and scale check, then replace every default value with your own inputs.

Why does rounding matter for result?

Rounding affects the displayed answer and can compound if you reuse the number. Keep more precision for intermediate work when the next step depends on it.
