Hypotheses

Ref	Expression
curfval.g	|- G = ( <. C , D >. curryF F )
curfval.a	|- A = ( Base ` C )
curfval.c	|- ( ph -> C e. Cat )
curfval.d	|- ( ph -> D e. Cat )
curfval.f	|- ( ph -> F e. ( ( C X.c D ) Func E ) )
curfval.b	|- B = ( Base ` D )
curf1.x	|- ( ph -> X e. A )
curf1.k	|- K = ( ( 1st ` G ) ` X )
curf11.y	|- ( ph -> Y e. B )

Assertion

Ref	Expression
curf11	|- ( ph -> ( ( 1st ` K ) ` Y ) = ( X ( 1st ` F ) Y ) )

Proof of Theorem curf11

Dummy variables g y z are mutually distinct and distinct from all other variables.
