Line Integral Puns

We were wondering what the most advanced calculator was that we can still use in exams.

Our teacher showed us a calculator with a lot of advanced features (e.g. differentiation, integration, matrices) and said "You're allowed to use ones like these but I don't think you can have graphing calculators."

To which I said "So that's where they draw the line."

I recently subscribed to this sub and it's my new favorite. I shamelessly stole the "tan line" joke for Facebook and a nerd volley with another dad ensued quickly.

Me: Wow, this warmer weather is getting me ready for spring. Hey, I'm already getting ready for summer, check out my tan line! <graph of tangent>

Him: It's certainly not a farmer's tan line...not straight enough.

Me: No farmer's life for me. It's not something I'd sine up for.

Him: ...and I wouldn't cosine your startup loan. (groan)

Me: Sheesh, there's no reason to be hyperbolic.

Him: I really must learn how to integrate all your math vocabulary into my daily life.

Me: You'd really have to think of some way to differentiate yours from mine.

Him: heh...maybe after I move to the delta and crawl under a natural log. I'm sorry, it just struck me that I'm acting the total asymptote.

Me: Ugh. The average of the posts in this thread is degenerating.

Him: We've traversed a slippery slope and while I don't mean to be mean we've gone way past the apex of this thread.

My wife: Nerds.

Me: You married me.
