Theorem pserval2 26432
Description: Value of the function 𝐺 that gives the sequence of monomials of a power series. (Contributed by Mario Carneiro, 26-Feb-2015.)
Hypothesis
Ref Expression
pser.g 𝐺 = (𝑥 ∈ ℂ ↦ (𝑛 ∈ ℕ0 ↦ ((𝐴𝑛) · (𝑥𝑛))))
Assertion
Ref Expression
pserval2 ((𝑋 ∈ ℂ ∧ 𝑁 ∈ ℕ0) → ((𝐺𝑋)‘𝑁) = ((𝐴𝑁) · (𝑋𝑁)))
Distinct variable groups:   𝑥,𝑛,𝐴   𝑛,𝑁
Allowed substitution hints:   𝐺(𝑥,𝑛)   𝑁(𝑥)   𝑋(𝑥,𝑛)

Proof of Theorem pserval2
Dummy variable 𝑦 is distinct from all other variables.
