Scientific Calculator
Perform common scientific calculations using one value and a selected mathematical operation.
How it works
- Square and square-root operations use standard arithmetic functions.
- Trigonometric calculations convert degree input to radians before evaluation.
- Natural and base-10 logarithms require a positive input value.
Example
Enter 30 and select sine to calculate sin(30°), which equals approximately 0.5.
Frequently asked questions
Are angles entered in degrees?
