Description: Exhibit a function  G with the same convergence properties as the not-quite-function  F. (Contributed by Mario Carneiro, 31-Jan-2014.)
Hypotheses
Ref Expression
2clim.1  |-  Z  =  ( ZZ>= `  M )
climmpt.2  |-  G  =  ( k  e.  Z  |->  ( F `  k
) )
Assertion
Ref Expression
climmpt  |-  ( ( M  e.  ZZ  /\  F  e.  V )  ->  ( F  ~~>  A  <->  G  ~~>  A ) )
Distinct variable groups:    A, k    k, F    k, Z
Allowed substitution hints:    G( k)    M( k)    V( k)

Proof of Theorem climmpt
Dummy variable  m is distinct from all other variables.
