Toggle DEG (degrees) / RAD (radians) as needed, then type your expression
2
Combine sin/cos/tan/log/ln/√/^ function keys with parentheses
3
Press "=" or Enter for the result; click a history entry to reuse it
🔢Supported operations
- Trig: sin/cos/tan (affected by DEG/RAD)
- Log & power: log (base 10), ln, ^, √, n!, 1/x, %
- Constants: π, e; parentheses and operator precedence
💡Tips
- Check DEG/RAD before trig functions — results differ greatly
- ×10ⁿ is for scientific notation, e.g. 6.02×10^23
- Invalid expressions or division by zero show an error without crashing
