Nuprl Rule : imageMemberEquality

This rule proved as lemma rule_image_member_equality_true in file rules/rules_image.v
 at https://github.com/vrahli/NuprlInCoq  

H  ⊢ (f a1) (f a2) ∈ Image(A,f)

  BY imageMemberEquality ()
  
  H  ⊢ a1 a2 ∈ A
  H  ⊢ f ∈ Base



Definitions occuring in rule :  image-type: Image(T,f) apply: a equal: t ∈ T base: Base axiom: Ax

Latex:
H    \mvdash{}  (f  a1)  =  (f  a2)

    BY  imageMemberEquality  ()
   
    H    \mvdash{}  a1  =  a2
    H    \mvdash{}  f  =  f
