Scientific Calculator
One Keypad, Eleven Functions
A scientific calculator earns its name by going beyond the four basic operations into roots, powers, logarithms, and trigonometry — the functions that show up constantly in physics problem sets, engineering calculations, and finance formulas. Rather than switching between a plain calculator for arithmetic and a separate tool for exponents or logs, this one enters a single number and applies any of eleven operations to it.
The Formula
Each mode applies a distinct mathematical function to the entered number (x):
Square: x²
Cube: x³
Sine / Cosine / Tangent: sin(x°), cos(x°), tan(x°)
Log base 10: log₀₁₀(x)
Natural Log: ln(x)
Exponential: e^x
Absolute Value: |x|
Factorial: x!
Square root rejects negative inputs, logarithms require a positive number, and factorial is capped at 1000 to keep results computable — each mode enforces the domain restrictions that make the underlying math valid.
Where This Range of Functions Gets Used
- Physics and engineering coursework — trigonometric functions for angles and vectors, exponentials for growth and decay models.
- Statistics and probability — factorials feed directly into permutation and combination counts.
- Finance — natural log and exponential functions appear in continuous compounding and growth-rate calculations.
| Function | Input | Result |
|---|---|---|
| Square Root | 144 | 12 |
| Cube | 5 | 125 |
| Sine | 30° | 0.5 |
| Log₀₁₀ | 1000 | 3 |
| Natural Log | e (≈2.71828) | 1 |
| Factorial | 10 | 3,628,800 |
