Simple limit but most students cannot prove it!

$How to find a formula for delta (epsilon-delta definition of a limit) We will prove that the limit of x^2 is 4 as x goes to 2 with the epsilon-delta definition. We will also do it without the usual trick (setting deleta=min{1, something}). Will this be any easier? No. Heres part 2: https://youtu.be/pk7vxTbKpxk A special life update: https://www.patreon.com/posts/142823922 🛍 Get your limit definition sweatshirt: https://a.co/d/9vJbK0i 👉 Support this channel and get more content https://www.patreon.com/blackpenredpen$
