Formula and methodology
Formula: For y=kx, output y = variation constant k × input x.
Direct variation has a fixed ratio y/x, so changing x scales y by the same factor.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Variation constant k — minimum -1000000; maximum 1000000
- Input x — minimum -1000000; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Variation constant k | 3 |
| Input x | 5 |
y = 15.
Assumptions and limits
- The relationship is modeled as y=kx with zero intercept.
- The constant and input are finite quantities with compatible units.
- The calculator does not fit k from observations or test causal proportionality.
