Overview
A fully functional scientific calculator supporting arithmetic, trigonometric functions (sin, cos, tan), logarithms, exponents, roots, factorial, and mathematical constants (π, e) — all in your browser.
How to use this calculator
- Type an expression or use the on-screen buttons.
- Use Deg/Rad toggle to switch between degree and radian mode for trigonometric functions.
- Press = or Enter to compute the result.
- Use Shift/2nd for inverse functions (arcsin, arccos, arctan, 10^x).
Understanding the inputs & results
sin / cos / tan
Trigonometric functions expressing the ratio of sides in a right triangle.
log
Logarithm base 10 (common log). ln = natural logarithm (base e).
x^y
x raised to the power y. E.g., 2^10 = 1024.
√x
Square root of x. The n-th root = x^(1/n).
n!
Factorial — product of all positive integers up to n. 5! = 120.
The formula
Key scientific formulas
sin, cos, tan, log, ln, e^x, x^y, √x, n!
All standard scientific calculator functions. Trigonometric functions can operate in degree or radian mode — toggle with the Deg/Rad button.
Worked example
Calculate sin(30°).
- Ensure Deg mode is selected.
- Enter sin(30) = 0.5.
✓ sin(30°) = 0.5.
