About the Scientific Calculator
This online scientific calculator brings together trigonometric functions (sine, cosine, tangent), logarithms, exponentials, roots, powers, factorial and constants such as π and e. It is free, runs in your browser and requires no installation or sign-up.
You can switch between degrees and radians for trigonometric calculations, which is essential in mathematics, physics and engineering. Expressions follow the order of operations, letting you combine several functions in a single calculation.
Frequently asked questions
What is the difference between degrees and radians?
They are two units of angle. A full turn equals 360 degrees or 2π radians. Use the DEG/RAD button to choose the unit before computing trigonometric functions.
Does the calculator follow the order of operations?
Yes. Multiplication and division are resolved before addition and subtraction, and parentheses take priority, following standard mathematical rules.
How do I calculate factorials or powers?
Use the factorial operator (!) after the number and the power operator (^) between the base and the exponent, for example 5! or 2^10.
Do I need to install anything to use it?
No. The calculator runs entirely in your browser, on any device, with no installation, sign-up or cost.
