    Symbol
In summary, the symbol in question is the German upper case letter J, which is used to represent the imaginary part of a complex number. This was discussed in a video by Carl Bender and is often denoted as ##\Im## or ##\mathfrak{J}##.

What exactly is the name and operation of the symbol that is found right after the approximately equal sign in the attachment? I have come across it a lot in readings, and I feel like I should clear up what it is.

The imaginary part?

What book were you studying? That may give us a clue.

On "the approximately equal sign"... watch Carl Bender @ 50:10 - 51:10

Dexitify gives ##\Im##. German J looks like ##\mathfrak{J}##.
Agree with micromass. The imaginary part makes sense contextually as well (approximating the derivative along the imaginary axis).
