That's because they're not on spec.

I have seen them in a C4 paper once, but admittedly ther're very uncommon

If you did, it was on an old-ish paper, it's literally not on spec anymore. (I think since around 2009/before then?)

I'm not sure exactly as it was in my mock which was a compilation of different papers. It was quite a nice question tbh, there may have been other ways of doing it without doing factor formulae if they're not on the spec. The question was number 9 of this document if anyone wants to look at it https://mathsmartinthomas.files.wordpress.com/2015/02/c4-parametrics-2.pdf

I hate things like this, that have only been on 1 past paper before.

I hope nothing new comes up in the exam

Yes, you can be asked regarding collinear points in Vectors.

I can't find anything in the c4 book about collinear points??? You got a page reference?

Just so you know, dm isn't direct method, but a method mark that is dependent on a method mark before, i.e. you can only get that method mark if you've scored the method mark before :smile:

They don't necessarily have to test from the book, Collinear points are those which lie on the same straight line. It's not a hard concept.

Calling all maths wizards: how do I do part a

I noticed the two sides given add up to 13 so tried to set up like cos and sin expressions using the angles and sides given and add them but got nowhere. I also tried to call the rectangle sides y and use the fact perimeter of shaded is 26 but I just ended up cancelling the 'y's....
