Newton-Raphson Idea @MathVisualProofs

Uploaded January 2026 | Updated September 2026, 2 weeks ago

In this short, we briefly discuss the idea behind the Newton-Raphson method for finding zeroes of functions (where the graph crosses the x-axis). The key idea is to use the tangent line over and over in an iterative process.

$Manim Tutorial: Hilbert Curve and L-Systems This is fifth video in a series inspired by the Talking Maths in Public group, I am trying my hand at showing how I create animations using 3blue1browns (Grant Sandersons) Python library ManimGL. The Talking Maths in Public Group encouraged creators to share how they would animate Hilbert Curves. In this video, I code in real time to create an L-system that draws out a level 4 and level 5 Hilbert Curve. In a previous video, I used this process to animate drawing a level 8 Hilbert Curve: https://youtu.be/xfuvkGSk8hs Let me know if you would like to see more how-to-animate math videos in the future.
