Let C be a category. (a) Define what it means for C to be closed under arbitrary products, i.e., define what it means for C to have a product $\prod_{i \in I} A_i$ for every family $(A_i)_{i \in I}$ of objects in C.

Step 1
Step 1: A category C is said to be closed under arbitrary products if for every family of objects {A_i} in C, there exists a product object P and projection morphisms π_i : P → A_i such that for any other object X with morphisms f_i : X → A_i, there exists a Show more…

The $\epsilon-\delta$ definition of a limit states, in part, that $f$ is defined everywhere in an open interval containing $c,$ except possibly at $c$. Discuss the purpose of including the phrase, except possibly at $c$, and why it is necessary.

The $\varepsilon-\delta$ Definition of Limit
Writing The definition of limit on page 42 requires that $f$ is a function defined on an open interval containing $c,$ except possibly at $c .$ Why is this requirement necessary?
