How do I annotate variables using epsilon? Like if I wanted to say the variable "t" is a member of integers, is that tEz? My professor is using a similar analog, except it's the letter C underlined, describing a function of vectors.

It's not epsilon. I know they look very similar though! :)
$$\Large t \in \mathbb Z$$Translates to:
t `in` Z.
Or the way you said it works well also, t `is a member of` the integers.

The sideways C is a little different.
$$\Large t \subseteq S$$We would translate to:
t `is a proper subset` of S
