What this calculator does

This scientific calculator handles common expressions such as powers, roots, logarithms and trigonometry. It is designed for quick checks rather than formal symbolic maths.

Formula used

Expressions are evaluated with standard order of operations. Trigonometric functions can use radians, or degrees when a number is followed by deg inside a function.

How to read the result

For exams, coursework or engineering work, check whether your context expects radians, degrees, significant figures or exact symbolic answers.

Assumptions

  • Supports sin, cos, tan, sqrt, log, ln, abs and powers.
  • Uses JavaScript number precision.
  • Does not support variables or symbolic rearranging.

Sources and checks

This calculator uses a standard public formula. Where rules or thresholds can change, source links are listed on the relevant page.

Frequently asked questions

How do I enter powers?

Use the caret operator, for example 2^8, or use sqrt for square roots.
