Finds foci of hyperbola. For x²/a² - y²/b² = 1, foci are at (±c, 0) where c = √(a² + b²).
For x²/a² - y²/b² = 1:
Foci: (±c, 0) where c = √(a² + b²)
For y²/a² - x²/b² = 1:
Foci: (0, ±c) where c = √(a² + b²)
Distance from center to focus = c
Foci coordinates from hyperbola equation

Interpreting results
If hyperbola focus looks implausible, re-check units and which field is optional vs required.
Assumptions
- The wired execution function for `hyperbola-focus-calculator` is the source of numerical behavior.
- Inputs for `hyperbola-focus-calculator` follow the on-page labels; values/shapes must match this operation.
- Real-number arithmetic is used unless hyperbola focus explicitly needs integers.
Limitations
- Display rounding can differ slightly from a CAS/symbolic exact form of hyperbola focus.
- Edge cases outside the intended domain of hyperbola focus may error or look unstable—treat them as out of scope.
- Complex/branch cuts and undefined points are not always interactively annotated for hyperbola focus.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
