Math Graphing Set B 05 Circle Equation Centre and Radius By Completing the Square Short Cut

Repeated revision and consolidation are so important to student success. This is a brief video in just repeating the basics of the Equation and details of graphing a circle. If they struggle with the Algebra involved with 'Completing the Square' it causes students to doubt their understanding. I have especially produced a separate video on 'Completing the Square' for this purpose.

After 40 years of enjoyable and rewarding teaching, I still love and continue to teach. It still amazes me how I continue to still think of better ways of teaching mathematical concepts and I also continue to discover methods of explaining things that help students 'better' understand and become more successful at remembering the concepts.

A word of warning from what I have repeatedly seen over the years - most of my videos are placed in a logical or reasonably sequential order and if you watch the first or second video in a playlist and feel comfortable with the concepts, please go to the last video in the playlist to check if you really are okay. Each video in a playlist usually becomes progressively more complex and the 'latter' or 'last' video will often contain common assessment questions where students are known to make errors.

I also often include some revision / consolidation / mixture videos in the playlist which I know are crucial to assist with student success in assessments.

I hope that you find this very helpful and a blessing in your studies.
