Are the trigonometric functions in degrees or radians?

This calculator uses radians. To convert degrees to radians, multiply the degree value by π/180 before entering it.

What's the difference between log and ln?

log is the base-10 logarithm, while ln is the natural logarithm using base e, commonly used in calculus.

What is the Scientific Calculator?

This Scientific Calculator handles everything a standard calculator does, plus trigonometric functions (sin, cos, tan), logarithms, square roots, powers and constants like π — all directly in your browser.

How to Use the Scientific Calculator

Tap the number and operator buttons to build your expression, just like a physical calculator.
Use function buttons — sin, cos, tan, log (base 10), ln (natural log), √ (square root), x² and xʸ (power) — to apply advanced operations.
Press "=" to evaluate, "C" to clear everything, or "CE" to delete the last character.

Available Functions

Trigonometric: sin, cos, tan (radians)
Logarithmic: log (base 10), ln (natural log)
Power & roots: x², xʸ, √
Other: 1/x (reciprocal), ± (sign toggle), π (pi constant)

Frequently Asked Questions

This calculator uses radians, matching standard JavaScript math functions. To convert degrees to radians, multiply by π/180 before entering the value.

"log" is the base-10 logarithm, commonly used in science and engineering. "ln" is the natural logarithm, using base e (≈2.71828), common in calculus and growth/decay calculations.
