Math Calculus Set A 02 Differentiation Introduction of Simple Cases

If you want to find my videos as topics in a playlist on Rumble, you can type in eg:
RobertPrestwidge Equation
RobertPrestwidge Trigonometry
RobertPrestwidge Fraction
Also Logs, Parabola, Quadratic, Index Laws, Exponents, Calculus, Surd, Order of Operations, Simultaneous Equations, Negatives, Trinomials, Factorising and many other Math topics.

You can also find me on Youtube where my videos are organised into Playlists ie Topics.

This is a simple and basic introduction to the operation of Differentiation.

This is invaluable revision and confidence building for 11 Methods / NSW Advanced.

By the way, if you view any of my videos on Rumble, all or at least most of my videos on that topic come up. This is where it is so important that I have my videos organised in 'Sets' and 'Numerical Order' so that you can see what comes next.

On Youtube I am Robert Prestwidge with the space, but I have a playlist for each topic eg Calculus, Trigonometry, Fractions, Equations etc as well as 'Sections' for each Year/Grade/Course but Rumble will not allow me to do this, although, it's automatic playlist is quite impressive.

On Rumble you can just type in:
RobertPrestwidge Trigonometry
RobertPrestwidge Equations
RobertPrestwidge Logarithms
RobertPrestwidge Parabolas
RobertPrestwidge Exponent
RobertPrestwidge Quadratic
RobertPrestwidge Negatives
etc to get my playlists

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.
