Скачать или смотреть Limits of Multivariable Functions: The Two-Path Test Explained

Calculus 3 can be tricky! 🧠 In single-variable calculus, limits are easy—left and right. But in multivariable calculus, you can approach a point from infinite directions! 🌀

In this video, we visualize what it means to take a limit as (x,y) approaches (0,0). We explore why testing just the x-axis and y-axis isn't enough, and how to use the 'Two-Path Test' to prove a limit does NOT exist. 🚫

We also cover the famous counter-examples where straight lines trick you, but parabolas reveal the truth! 📉

Perfect for students in Calc 3, Vector Calculus, or anyone loving math visualization.
