How to learn Parametrics from start to end? (1 Viewer)

[pokemonlv10]

Hey guys, i'm having immense issues with learning parametrics for 3u maths. The teacher we had when learning the subject was no help and brushed past the topic in a few days. I can't seem to do any questions in the textbook and struggling with the basics.

Is there any links to a website that teaches this topic in full?

Thank you

It's not that bad you just need to do a few types of questions to get the hang of it. You can visualise some of the questions but I find it's easier to just do it with algebra. Don't forgot the golden rule, remove the parameter

Maybe there is like maths online or something? I think dux college also might have some free examples https://dc.edu.au/mathematics-extension-1-parametric-equations/

Hey Ben, thanks for the link, its alright so far! What do you mean by the golden rule - Remove the parameter?

Can you guide me through a common HSC question on Parametrics?
