Hypotheses
Ref Expression
tendoi.i 𝐼 = (𝑠𝐸 ↦ (𝑓𝑇(𝑠𝑓)))
tendoi.t 𝑇 = ((LTrn‘𝐾)‘𝑊)
Assertion
Ref Expression
tendoi2 ((𝑆𝐸𝐹𝑇) → ((𝐼𝑆)‘𝐹) = (𝑆𝐹))
Distinct variable groups:   𝐸,𝑠   𝑓,𝑠,𝑇   𝑓,𝑊,𝑠
Allowed substitution hints:   𝑆(𝑓,𝑠)   𝐸(𝑓)   𝐹(𝑓,𝑠)   𝐼(𝑓,𝑠)   𝐾(𝑓,𝑠)

Proof of Theorem tendoi2
Dummy variable 𝑔 is distinct from all other variables.
