Proof of proveit.logic.booleans.implication.eq_from_iff theorem¶
In [1]:
import proveit
# we need to import these to derive their side-effects:
from proveit.logic.booleans.implication import true_iff_false_negated, false_iff_true_negated
theory = proveit.Theory() # the theorem's theory

%proving eq_from_iff
With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
eq_from_iff:
(see dependencies)
eq_from_iff:
