🔥 Top post @phonner Thank you for your post on AI use in your proofs class! I have cited your "don't let computers do your thinking for you" point several times today. ★ 4

Discrete math couldn't have been too discrete if so many people know about it. Just saying. ★ 2 The three approaches used were: 1. Counting surjections/bijections from the set $ \{1,2,\cdots,n\} $ to itself in two different ways 2. Using an exponential generating function and comparing coefficients 3. Using induction on finite diff… We live in a wonderful world where LLMs can generate proofs of Olympiad style math problems and explain them in excruciating detail if you don't understand them. Claude just bombed through this very tricky combinatorial identity in three d… ★ 1 I am quite proud of my answer to this question: "Is there a simple way to visualize or conceptualize Lebesgue integration that might help someone grasp it more intuitively?" https://www.quora.com/Is-there-a-simple-way-to-visualize-or-conce… ★ 1 How would you answer this question? Using the appropriate number of significant digits and units, what is 1.0m plus 2mm? __m Very frustrated with this answer! ★ 1 This is both hilarious and distressing. 0.002¢/kb is quoted before traveling to Canada, the actual rate is $0.002/kb. The customer calls to object to a charge of $71.76 for 35,893 kb in data usage instead of $0.7176 after receiving his bil… If you've seen this already, don't answer it - and if you haven't, try this out. Given two random variables X, Y from a uniform distribution $ [0,1] $, what is the probability that: 1. When rounded to the nearest integer, \(\frac{Y}{X… ★ 1 After session 2: I definitely need to replan this. We got through review, graphing tan(x), definition of radians and conversion to and from degrees, and special angles (generating sin, cos, tan of 30, 45, and 60 from square and equilateral… ★ 2 Would love to get math teacher feedback on this - too much in too little time? Ambitious but doable? My goal is to do this AoPS style - build understanding by getting him to do problems and "discover" the formulas with a minimum of exposit… Have I bitten off more than I can chew trying to bring him to understanding of all of these concepts? The first lecture went really well, I love teaching the shape of the trig functions with the unit circle, it makes it so much easier to u… ★ 1 And lecture 6 (if he's not sick of me already): More Trig identities: * Review angle sum, difference, double angle formulas, prove using geometry identities * Verifying trig identities such as \(\tan^2(x) + 1 = \sec^2(x), \cot^2(x) + 1 = \…
