Frequently Asked Questions

What functions does the Scientific Calculator support?

The calculator supports basic operations (+, -, ×, ÷), trigonometric functions (sin, cos, tan and their inverses), logarithmic functions (log, ln), power functions (x², x³, √, xʸ), factorial, constants (π, e), and memory functions (MS, MR, M+, MC).

How do I use trigonometric functions?

First, set the angle mode to DEG (degrees) or RAD (radians) using the DEG/RAD button. Then enter a number and click the desired trig function (sin, cos, tan). The calculator will compute the result based on the selected angle mode.

How do I use memory functions?

Use MS (Memory Store) to save the current value to memory. Use MR (Memory Recall) to retrieve it. Use M+ (Memory Add) to add the current value to memory. Use MC (Memory Clear) to clear memory. A small 'M' indicator shows when memory has a value.

Can I use my keyboard with the calculator?

Yes! The calculator supports keyboard input: numbers (0-9), operators (+, -, *, /), Enter for equals, Escape for Clear All, Backspace for delete last character, and parentheses keys ((), ).

Is my data secure?

Yes! All calculations are processed locally in your browser. No data is uploaded to any server, stored, or shared. Your calculation history is only stored temporarily in your browser session for your convenience.
