Autograph Video 55 – Transformation of Functions 2
Part 2 of the Transformations of Functions Trilogy of Autograph videos. This time we take a peek at a nice way of getting the exact shape function you are looking for without having to worryContinue reading
Autograph Video 54 – Transformation of Functions
The first in the Transformations of Functions Trilogy of videos where we look at how we can use Autograph to introduce students to the topic of transforming graphs. We see how to enter the f(x)Continue reading
Autograph Video 53 – Creating Number Lines
Following on from our work on worksheets last week, this time we take a look at how Autograph can be used to very quickly create an incredibly flexible number line. This can then be usedContinue reading
Autograph Video 52 – Creating Worksheets
Just a quickie here about how you can use Autograph to add that finishing touch to your perfect worksheet. Whether you want a lovely set of axes, some square paper, or some old fashioned graphContinue reading
Autograph Video 51 – Fitting Functions to Data
Following a request from Science teacher Mr Richardson, here is a video explaining how you can use Autograph to fit functions to various data sets. It doesn’t matter if the relationship in your data isContinue reading
Autograph Video 50 – Further Volumes of Revolution
In the final Autograph Video of 2011 we take a look at some of the lovely shapes you can make using Volumes of Revolution. We hint at how it is possible to derive the formulaeContinue reading
Autograph Video 49 – Volume of Revolution Formula
Following directly on from Video 48, this week we look at how we can use Autograph’s unique 3D engine to demonstrate to students exactly where the formula for the volume of revolution comes from. ThisContinue reading
Autograph Video 48 – Volume of Revolution Introduction
In my opinion, there is no better way of illustrating the concept of Volumes of Revolution to students than using Autograph’s unique 3D engine. Watch their delight at the area under the curve spins neatlyContinue reading
Autograph Video 47 – Further Integration
Following on from last week’s video, this time we look at how to use Autograph to cope with integration’s little twists, such as dealing with negative areas, working out the area between a curve andContinue reading
Autograph Video 46 – Integration – Area Under a Curve
This week we move from differentiation to integration by taking a look at how Autograph can be used to introduce students to the concept of the area under the curve. The good news is thatContinue reading
Autograph Video 45 – Tangents and the Gradient Function
This week we continue our look at the world of 2D graphing by examining how we can use the tangent tool and the gradient function to investigate quadratic curves. This offers a slick way ofContinue reading
Autograph Video 44 – Iteration
Following a request from Mr Howard of Bolton School, this week we look at how Autograph can be used to help students visualise how the iterative process works. We look at three different examples whichContinue reading
Autograph Video 43 – Graphing Quadratics
We are going to be looking at graphing on Autograph for the next few weeks, and what better way to start than by looking at some of the different ways we can represent quadratic equationsContinue reading
Autograph Video 42 – Coins and the Geometric Distribution
Continuing our theme of all things statistical, this week we take a look at how Autograph might be used to introduce students to the concept of the Geometric Distribution, with a little helping hand fromContinue reading
Autograph Video 41 – Dice and the Binomial
In this video we continue our look at statistics and probability by seeing how Autograph can be used to introduce the concept of the binomial distribution. We look at the classic example of tossing aContinue reading
Autograph Video 40 – Biased Dice & Balls in a Bag
This week we take a look at how Autograph can be used to introduce students to the concept of experimental probability. You can very quickly set up a probability distribution function of your choice (fairContinue reading
Autograph Video 39 – Extras – Trigonometry
In this video we take a look at the third of Autograph’s wonderful Extras pages – Trigonometry. Here we see where the graphs each of the trigonometric ratios comes from using the unit circle, andContinue reading
Autograph Video 38 – Extras – Monte Carlo Method
In this video we take a look at the second of Autograph’s wonderful Extras pages – the Monte Carlo Method. We see how this can be used to make an estimate for the value ofContinue reading
Autograph Video 37 – Extras – Dice Simulation
This week we take a look at one of the excellent Autograph Extras pages. The Dice Simulation page is fantastic for allowing your students to explore the concepts of experimental probability, sample sizes and distributions.
