This week we look at our second Circle Theorem – this classic Cyclic Quadrialteral Theorem. After quickly constructing and demonstrating the theorem, we also have a look at a nice little extension question involving parallelograms…

Autograph Video 18 – Angle at the Centre
Whilst we are on a roll with the Angle at the Centre Theorem, why not have a quick look at a nice little twist? We can use Autograph to set up some circumstances where theContinue reading
Autograph Video 17a – Angle at the Centre
This week we take a look at how to construct Circle Theorems using Autograph, beginning with the Angle at the Centre Theorem. We also see how understanding this theorem leads us to another theorem forContinue reading
Autograph Video 17 – Circle Theorems
This week we take a look at how to construct Circle Theorems using Autograph, specifically the angle at the centre theorem. There is also a brief look at tangents, all of which should arm youContinue reading
Autograph Video 16 – Working with Grouped Data 2
I know I said last week was the last data one, but a request came through on the emails, so I thought I had best cover it whilst we are on a roll! So, thisContinue reading
Autograph Video 15 – Working with Grouped Data
In our final look at data for a while (you can have too much of a good thing) we tackle an issue with commas and how to alter the sizes of your groups. Subsribe toContinue reading
Autograph Video 14 – Valentine’s Day Special
In a special “loved-up” edition of Mr Barton’s Autograph videos, we look at a romantic (mathematical) alternative to chocolates and flowers to send to the love of your life to let them know you care.Continue reading
Autograph Video 13 – Working with Raw Data 4
In a jam-packed edition we start to look at how Autograph can group raw data for us and how this opens up a whole new set of possibilities in terms of mathematical diagrams, including cumulativeContinue reading
Autograph Video 12 – Working with Raw Data 3
Douglas Butler returns again! This time with a great suggestion for introducing the Normal Distribution via a look at the fascinating world of IQ. The also encompasses Autograph’s wonderful scaling option for nasty looking data!Continue reading
Autograph Video 11 – Working with Raw Data 2
Following a suggestion from none other than Autograph creator Douglas Butler, we take another look at some of the things you can do with Raw Data on Autograph, including quickly creating a data set. MoreContinue reading
Autograph Video 10 – Working with Raw Data
This week I deal with a request from Lucius Evans who wanted to look at some of the Statistical functions on Autograph. Here I deal with a request from Lucius Evans who wanted to lookContinue reading
Autograph Video 9 – Measuring Angles
This time we look at the basics of measuring angles in Autograph.
Autograph Video 8 – Christmas Special
A Special Christmas Edition of Mr Barton’s Autograph Videos which has a look at the online Autograph Player (with a festive twist!). To have a play with the file yourself, just visit: http://www.autograph-maths.com/simon/…
Autograph Video 7 – Edit Axes
This time we take a closer look at the Edit Axes menu to get our Autograph page looking exactly how we want it.
Autograph Video 6 – Combined Transformations
This time we look at how we can use Autograph to combine Transforamtions, and there is even a little puzzle for you to have a think about…
Autograph Video 5 – Translation
This time we complete the set of Transformations by looking at how we can carry out Translations in Autograph. Mr Barton also sorts out the screen size issue!
Autograph Video 4 – Enlargement
In this video we look at how we can carry out Enlargements in Autograph, which also leads us to our first viewing of a Dynamic Text Box!
Autograph Video 3 – Rotation
In this video we look at how to carry out Rotations in Autograph 3.3.
Autograph Video 2 – Reflection
In this second video we look at three different ways of doing Reflections in Autograph.
Autograph Video 1 – Shapes
In this first video we look at the issue of Whiteboard Mode and how we go about creating basic shapes.
