advice from a math YouTuber. Here are some tips on how to use YouTube in your teaching and how you can start your own YouTube channel. This is the talk I was supposed to give at the 2022 Joint Mathematics Meetings before it got cancelled. Spreading the math: using YouTube to communicate with the rest of the world.

$Anti Pythagoras 2: the Line, Ellipse, and Infinite Triplets Anti Pythagoras 2: the Line, the Ellipse, and the Infinity. How to generate infinitely many anti Pythagorean triplets of the form b^2 = a^2 + c^2 - ac The triplets relate the sides of a triangle where one angle is 60 degrees. It is a variation of the Pythagorean theorem from 8th grade math. It has to do with intersecting an ellipse with a line of rational slope and performing some clever algebra like expanding quadratic polynomials and quadratic forms and comparing numerator and denominators of fractions with integers. Then we give an example of a triangle with such a triplet. Special thanks goes to Ian Fowler who has introduced me to this problem. Ian would like to give a big shout out to Emidio Iacobucci and Frank Cirone for their part in the adventure. 0:00 Introduction 1:40 Rational Slopes 2:40 Finding Nemo 6:00 The triplets are born Anti Pythagorean theorem: https://youtu.be/TMR1oYkCKEs YT channel: https://youtube.com/drpeyam TikTok channel: https://www.tiktok.com/@drpeyam Instagram: https://www.instagram.com/peyamstagram/ Twitter: https://twitter.com/drpeyam Teespring merch: https://teespring.com/stores/dr-peyam$
