❓ Frequently Asked Questions
How do I use DEG vs RAD mode?
Click the DEG/RAD button to toggle. DEG (degrees) is the default. When using trigonometric functions like sin, cos, tan, the input is interpreted in the current angle mode. For example, sin(45) in DEG mode returns 0.7071, while in RAD mode it returns 0.8509.
What does SHIFT do?
SHIFT toggles between primary and secondary functions. When SHIFT is active, sin becomes asin (arcsine), cos becomes acos, tan becomes atan, log becomes 10^, and ln becomes e^. Press SHIFT to activate/deactivate.
How do I use Matrix mode?
Switch to MATRIX engine via the MODE button. Click "Mat A" or "Mat B" to enter matrix values (2×2 or 3×3). Then use operations: det(A), inv(A), T(A), A+B, A×B to compute results.
How does Complex number mode work?
Switch to COMPLEX engine via MODE. Enter complex numbers using 'i', e.g., "3+4i". Operations are performed in complex arithmetic. Results show both real and imaginary parts (e.g., "3+4i").
What functions are supported?
All standard scientific functions: sin, cos, tan, log, ln, sqrt, exp, abs, nCr, nPr, factorial (!), plus constants π and e. Use parentheses for grouping: 2*(3+4). Order of operations (PEMDAS) is respected.
How do I use Memory (M)?
M+ adds current result to memory, M- subtracts, MC clears memory, MR recalls. You can also use 'M' in expressions. The memory value persists until cleared.
