This video looks at how to define the circular functions using the unit circle. It explains where each of the identities comes from and how the can be used for find a range of angles between 0 and 360 degrees.

This video looks at how the Pythagorean Identity came into existence and how it can be used to find solutions to trig equations using the unit circle.

This video recaps all the important points which have been covered in Methods 1 and 2. It deals with the general forms of each trig function and then moves onto the ideas behind transformations.

This video shows how you can solve trigonometric equations. It looks at the number of solutions which might be possible over a given domain. It looks at how to find the initial solution and a number of different ways of then finding all the other solutions.

This video shows how to transform sine and cosine curves. This is really important information which is used in VCAA VCE Methods exams all the time. The ability to know how to transform sine and cosine curves is really important. Discusses how the period and amplitude are affected. This video is also available on my dedicated maths website: http://www.maffsguru.com Whilst I have created this video for my students in Australia, I know it will be a good maths video for high school students in the USA and UK too.

Do you find yourself asking what a circular function is? Do you wonder at how to determine the rules for circular functions? Well, this is the video for you. It takes a chilled look at finding equations of circular functions when we are given the general form of the equations and important information on either a graph or in a question.

We have spent a lot of video time talking about sine and cosine functions - which are really important in terms of understanding for the exams and possible SAC questions. We now take a look at the tan function in terms of what it looks like, how it can be transformed and how it can be used to help solve trig functions.

This video looks at finding the general solution of trigonometric functions. It looks at it from a first principles approach by looking at some popular sin, cosine and tangent values and using them to find all the solutions. The video ends by looking at some questions and how exams might use the general solutions to test understanding

These are the videos which are available in each chapter. You will notice that some are free and some are for subscribers only. Making and hosting these videos costs a little bit of money. To help pay for the hosting fees I have no choice but to hide some of the videos and make them for subscribers only.
