Completing nature tables

A worksheet to focus in on the process of constructing a nature table (table of signs) and using it to determine the nature of stationary points.

In my experience, pupils find learning the process of finding and characterising stationary points challenging to learn as a complete process, so breaking it down into discrete elements gives a chance to become comfortable with each part before bringing it all together.

Modelled on the answers expected for Scottish SQA Higher Maths, but also applicable elsewhere.
