This is a simple introduction and understanding of how to factorise a trinomial. This normally comes into year 9 and 10, especially in the higher level classes. It is often used in the more academic Senior Maths Courses anywhere in the world. Furthermore, it is actually used as a method to solve equations as well as to simplify more complex fractions. 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.

This is the first video in the new set which goes through the basics of how index law ‘1’ works, using Algebra. I give students verbal pictures and simple explanations that help students to understand and remember the concepts, as well as warn them about the common errors and misunderstandings. This is the first of many short videos in this playlist. If it is too simple, jump ahead to videos 2, 3 or 4 etc. There are also revision videos included in this playlist to help you understand better and not get confused into making errors. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach.

Index Laws are s commonly misunderstood section of Algebra. This goes through a mixture of the first 3 videos to help make sure that your understanding is good. I know it is very important to give students an opportunity to consolidate and make sure that you don’t get things ‘mixed up’. I give students verbal pictures and simple explanations that help students to understand and remember the concepts, as well as warn them about the common errors and misunderstandings.

This is the last of the videos presently in this set. By now this has covered the most common school level cases. So many students struggle with the basic concepts. I use my own special little ways to help students understand the concepts and facilitate their success with equations. So many students ‘fight’ showing working out, but it is the only way to a successful future in solving equations and I’ve never seen an exception in over 5,000 students! The goal of showing working out is to establish your proficiency so that you end up comfortable with ‘short-cutting’ on the solving of equations. I have made another playlist of equations which explains the simpler ‘2 Step Equations’. This new list starts to look at the slightly harder cases where there is an unknown ie ‘x’ on both sides of the equal sign of the equation. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach.

So many people have struggled with understanding Trig and while teaching it uncounted times, I have trialled many different approaches. Students wanting to become an electrician in Australia, have to be proficient with Trig and it also comes into many unexpected areas of life. for some people (nowhere near everyone). I used all of that experience to come up with the ‘order’ of teaching in these videos, which I am sure that some students will find invaluable to their success with Trig. There are 2 basic approaches in teaching Trig. I am now convinced that it is better to first do all three of Sine, Tan and Cosine where the equations formed all have the unknown on the ‘numerator’, so that they all have the same method of equations solving. I believe this reduces introducing further complexity, especially for students who struggle with it. Then calculate the angles, followed lastly by dealing with right-triangles where the unknown is on the denominator. This is much longer than I anticipated, but I am very happy with the finished product. After 40 years of enjoyable and rewarding teaching, I still love and continue to teach.

Over my forty years of teaching and tuition, so many people have struggled with understanding Trig and while teaching it uncounted times, I have trialled many different approaches. Students wanting to become an electrician in Australia, have to be proficient with Trig and it also comes into many unexpected areas of life. for some people (nowhere near everyone). I used all of that experience to come up with the ‘order’ of teaching in these videos, which I am sure that some students will find invaluable to their success with Trig. There are 2 basic approaches in teaching Trig. I am now convinced that it is better to first do all three of Sine, Tan and Cosine where the equations formed all have the unknown on the ‘numerator’, so that they all have the same method of equations solving. I believe this reduces introducing further complexity, especially for students who struggle with it. Then calculate the angles, followed lastly by dealing with right-triangles where the unknown is on the denominator. 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.
