Have you ever seen a definition of derivative that also deals with the epsilon-delta definition of limit? When you try to talk about them together, you need to rename a few things. The f(x) in the limit defn is not the same thing as the f(x) in the derivative defn (for one example). #Iteachmath

#iTeachMath ♾️ I'm writing a series of young adult novels / math books, Althea's Math Mysteries. There was an error in a proof in Althea and the Mystery of the Imaginary Numbers. I couldn't see how to fix it. So her mom mentions Andrew Wiles and the flaw that took him an extra year. 1/3

Kevin Warsh starts his tenure with his credibility in tatters. He's proven himself to be Donald Trump's sock puppet. And he refuses to answer who cut him a $100 million check for his secret investments – and what they may want from him as the new Fed Chair.

Just wanted to let you know that the IRS has audited every president annually for decades now to ensure there was no corruption and the reason you didn't know that was because only one president found that to be a problem

NEW: Among the more than 50,000 words in the DNC’s 192-page autopsy of why it lost the 2024 presidential election, here are a few that do not appear even once: Gaza, Israel, Palestine, Jewish, Muslim, foreign policy, protest, genocide. www.motherjones.com/politics/202...

There are 50,000 words in the DNC autopsy. 'Gaza" isn't one.

Just unbelievable corruption. He said he would drain the swamp, instead he brought in the swampiest administration in history, declared himself Supreme Emperor of Swampopia, and ordered his justice department to essentially give his entirely family immunity.

Of all of Biden’s failures to meet the moment, few piss me off more than his not using SCOTUS’s “presidential immunity” ruling to cancel student debt. Especially after the election. He had four months to cancel it and delete the records!!! What were they going to do? Impeach him? Lol
