Ride the Rollercoaster with the Mathwise Calculus Cluster

If NAG the company which markets Mathwise is looking for a logo for the calculus cluster they could do worse than choose the corkscrew rollercoaster at Alton Towers.

There is another sense in which this would be an appropriate logo for this package although this would probably make it not quite so appealing to NAG. A rollercoaster is characterised by its highs and lows and unfortunately the same is true of this package. In some places it is an excellent imaginative and appealing resource for learning about calculus whilst in others it is little more than an on-screen book heavily reliant on static algebraic explanations.
