Here's how a student integrated xcos(x) today. Her technique is pretty brilliant! I've never considered doing something like this before. pic.twitter.com/ZtiGbse5Z5

This morning I had a moment of finally understanding a mathematical idea that I've been thinking about for at least the past five years. Math is like that sometimes.

Me: <egregiously violating algebraic rules in erroneously simplifying exponential expression>

Student, politely, after raising hand: "Can you explain the laws of exponents you used here? I'm not familiar with them."

I always introduce non-separable differential equations by asking students to solve y' = x + y, which they generally aren't equipped to do. Occasionally students intuit an answer, but a student did this today, which I've never seen before. Brilliant!#math #mathchat #APCalc pic.twitter.com/xFI2n8DuUq

"For some reason, once you starting thinking about Calculus, you can never go back."

-Student reflection
July
I maintained a pretty stoic demeanor my first year of teaching but one notable exception was the day a student told me they preferred the Slope-Intercourse form of a line.

August
For the first time in 5 years my school year planning can begin with "Everything I need to do this year can be done as I did it last year". A welcome change!

A short thread on one of my favorite Pre-Calculus topics: Tangent Lines!
— Patrick Honner (@MrHonner) September 28, 2022
Given a polynomial P(x), divide by (x – a)² and write in quotient-remainder form. By the division algorithm, the remainder has lower degree than the divisor. This means the remainder is linear. pic.twitter.com/YLNzxHI40z

I am a mathematician. I also routinely count on my fingers to compute Friday's date when making my calendars.

November
Another fun thread about long division! We were discussing the arithmetic of complex numbers in precalculus, and I asked students how we would divide them. One student half-jokingly suggested we try long division. So we did!

I usually don't engage with trending topics here on Twitter, but in this case I'll make an exception: You can find me on #Mastodon at phonner@mathstodon.xyz.
