Assumptions
- Principal Solution is computed only from the fields you enter on this calculator. [principal-solution-calculator]
- The wired execution function for `principal-solution-calculator` is the source of numerical behavior.
- Real-number arithmetic is used unless principal solution explicitly needs integers.
Limitations
- Edge cases outside the intended domain of principal solution may error or look unstable—treat them as out of scope.
- If multiple conventions exist for principal solution, this calculator uses the convention implemented in its engine path.
- Complex/branch cuts and undefined points are not always interactively annotated for principal solution.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
