I was recently asked a "when would I ever use this" question (as it happens, the topic was finding the equation of the tangent to a circle) and I struggled to find anything when searching.
Does anyone know of a resource that lists GCSE topics (at the level of granularity in my example) with any associated applications? Ideally this would be a use that anyone might come across, or failing that, applications from specific employment fields.
I'm really looking only for a sentence that describes the use; any worked examples would be a bonus. I could then mention the use in the lesson, or at least have it to hand if asked.
I'm aware of the Maths in Work item (https://www.ncetm.org.uk/resources/11329), which is a great resource, but not quite what I'm after.
