Parametric Equations (2 Viewers)

[_luke_]

Hi all,

Currently in Year 11 and doing extension math. When doing parametric equations, is it better to derive the equations or try to memorise them?

Thanks in advance.

It is not a matter of which is better - you are not permitted to write them down without proof. The only exception is the chord of contact formula (or of course if they ask a multiple choice question on the topic).

And ..... in Australia we do maths.

I think that's it - being a teacher I have the luxury of not having to memorise it.

Look at the intro to Ex 9H in Cambridge year 11.

Deriving but after doing numerous questions, you end up remembering them anyways

Don't forget you're talking to a fossil. I have no idea what "ceebs" means.

I've never owned a suit.
And I haven't worn a hired suit for 26 years.
And I'm pretty sure I can't remember how to do up a tie.
