I'm talking about "real" again. This class is abstraction built upon abstraction in the form of the theory needed to bring rigor to the underpinnings of the calculus.
Does anyone reading this see the above notes as concrete?
The reason I titled this post "reality check" is because the author of this textbook needs a "real"ity check. Here is a sentence from the text that made me laugh out loud:
"A thorough understanding of these topics on the real line will prove invaluable when they are encountered in MORE ABSTRACT SETTINGS."
Um . . . if this isn't abstract, what is it?!
And to think my algebra students ask me where they are going to use ALGEBRA in REAL LIFE!
PS Antonio, the last time I posted about "real" you asked why I only included a "sentence" rather than a "paragraph." Here's your paragraph, and here's a little pop quiz to keep you sharp. What does the "paragraph" here prove?
