The formula, made clear.
Trigonometric inputs use degrees. Log uses base 10, ln uses base e, powers use xʸ, and factorial multiplies every positive integer from 1 through x.

When to use this calculator
Use the scientific calculator for schoolwork, engineering checks and advanced everyday maths. Select a function, enter x and—when calculating a power—enter exponent y.
See the calculation in context
Select Power, enter 5 as x and 3 as y. The result is 125. Select Sine and enter 30 to get 0.5 because angles are interpreted in degrees.
Frequently asked questions
Are trigonometric angles in degrees or radians?
This calculator uses degrees so common angles such as sin(30°) return familiar results.
Why does factorial reject some values?
Factorials require whole numbers from 0 through 170. Larger values exceed the practical numeric range of the browser.
What is the difference between log and ln?
Log uses base 10, while ln uses the natural base e.
