- relation: [ [ 1, 2 ], [ 2, 1 ], [ 2, 3 ], [ 3, 2 ] ]
- inverse: [2,1], [1,2], [3,2], [2,3]
- isSymmetric: true
About this calculator
Overview
Inverse Relation Calculator evaluates Inverse Relation for the math / sets-relations-functions library. Primary input cue: Relation R [required]: Relation as array of ordered pairs. Method anchor: R⁻¹ = {(b, a) | (a, b) ∈ R}. Inverse relation swaps the order of all ordered pairs.
When to use
Reach for Inverse Relation Calculator to compare scenarios by changing one input at a time for inverse relation.
Inputs explained
- Relation R [required]: Relation as array of ordered pairs
Formula / method
R⁻¹ = {(b, a) | (a, b) ∈ R}. Inverse relation swaps the order of all ordered pairs (calculator id: inverse-relation-calculator).
Worked example
Worked values: relation = [[1, 2], [2, 3], [3, 4]] → inverse = [[2, 1], [3, 2], [4, 3]], isSymmetric = False
Interpreting results
Cross-check with a simple numeric example before relying on extreme inputs for inverse relation.
Assumptions
- The wired execution function for `inverse-relation-calculator` is the source of numerical behavior.
- Inputs for `inverse-relation-calculator` follow the on-page labels; values/shapes must match this operation.
- Real-number arithmetic is used unless inverse relation explicitly needs integers.
Limitations
- Display rounding can differ slightly from a CAS/symbolic exact form of inverse relation.
- Edge cases outside the intended domain of inverse relation may error or look unstable—treat them as out of scope.
- Complex/branch cuts and undefined points are not always interactively annotated for inverse relation.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
