Wegstein's Method

The primary video covering Wegstein's Method can be found here https://youtu.be/T_6mR6rJXQQ. It requires knowledge of Fixed Point Iteration and its recommended that you watch the videos on Steffensen's Method with Aitken's Δ² and Fixed Point Iteration Q&A. The code for Wegstein's method is written in Kotlin and can be found in Wegstein.kt.

When the service is available you can run the program online through CodingGround or run it locally by having Kotlin installed https://kotlinlang.org/ and typing kotlinc Wegstein.kt -include-runtime -d Wegstein.jar and then running java -jar Wegstein.jar. I recommend using an IDE like Visual Studio Code with the Code Runner extension to execute Kotlin programs.
