| Description: Equality inference for function predicate with domain. (Contributed by NM, 4-Sep-2011.) |
| Ref | Expression |
|---|---|
| fneq2i.1 | ⊢ 𝐴 = 𝐵 |
| Ref | Expression |
|---|---|
| fneq2i | ⊢ (𝐹 Fn 𝐴 ↔ 𝐹 Fn 𝐵) |
| Step | Hyp | Ref | Expression |
|---|---|---|---|
| 1 | fneq2i.1 | . 2 ⊢ 𝐴 = 𝐵 | |
| 2 | fneq2 6631 | . 2 ⊢ (𝐴 = 𝐵 → (𝐹 Fn 𝐴 ↔ 𝐹 Fn 𝐵)) | |
| 3 | 1, 2 | ax-mp 5 | 1 ⊢ (𝐹 Fn 𝐴 ↔ 𝐹 Fn 𝐵) |
