Here is a YouTube video about Using the CORDIC Algo to Produce Sine and Cosine Functions, and is part of a growing collection of videos I have found to be useful. The reason is using a generic CORDIC to produce sine and cosine type outputs, usable in software defined radio and understanding science related to software defined radio.
This tutorial, "Using the CORDIC Algo to Produce Sine and Cosine Functions" is free education you can watch, which will help you deepen your knowledge and be better prepared for licence exams, schoolwork, or operating radio equipment.
