Question on the BOS Syllabus (1 Viewer)

Hi,

In the syllabus it states "The formula for the distance between two points should be derived, as should the formula for the perpendicular distance of a point (x1, y1) from a line ax + by + c = 0.". In a few other sections it also talks about deriving the formula.
Does this mean we should be able to derive the formula ourselves?
That in a test they might ask that?

Thanks

Yep.

Definitely.

Is it likely they will ask a question about deriving a formula? Has it happened before?

Very rarely. But you still need to understand how it works though. Hence why teachers go through the proof of the formula.

Ok, should I remember and memorise the proofs?

I think it's unlikely they'd get you to derive the perpendicular distance formula.

That was meant solely as an example. For any other level of mathematics and formulas and results should I memorise the proofs?

Who knows, now that they have the reference sheet, they may start to ask for more proofs in exams??

Does anyone think that this may be the case?

I didn't realise this was in the syllabus, so thanks for bringing it up.

Some proofs/derivations get asked very often in exams (e.g. 4U deriving equation of tangent to conics), which you'll probably end up remembering just by practising past papers enough.

Which ones did you have in mind? Things like proofs of compound angle formulas, calculus rules (like product rule) etc. would be unlikely to be asked as proofs I think.

Take a look at the syllabus, it says which things students are expected to know how to prove, I think.
