Scientific Calculator — Trigonometry, Logarithm and More

Going beyond the four basic operations, this scientific calculator supports sin, cos, tan and inverse trigonometric functions, natural logarithm (ln), base-10 logarithm (log), exponential functions (eˣ, 10ˣ), square/cube and square/cube roots, factorial (n!), absolute value and memory storage.

How to Use

Enter a number, then press the function button you want to apply — the result is displayed instantly. For two-operand operations (+, -, ×, ÷, xʸ), enter the first number, select the operator, enter the second number and press = or Enter. Change the angle unit with the DEG/RAD button. Keyboard shortcuts are also supported.

Supported Functions

Frequently Asked Questions

In DEG (degree) mode, angles are measured in the 0–360 range; it is widely used in everyday life and engineering. In RAD (radian) mode, angles are measured in the 0–2π range; it is preferred in advanced mathematics and physics. Use the DEG/RAD button in the top right to switch between modes.
