Tbh. Seems like it. Sorry if this comes off as arrogant i dont mean it to be.

Oh no. It doesn't

If it asks for a matrix's transformation in words, how do we know what this is?

Posted from TSR Mobile
A sketch shoukd present the transformation.
In general transformations can be take as ksin/costheta in the rows of the matrix. Equation to two elements presents the k and theta.

3. June 2013 R is a paper worth doing. Fairly monstrous integration by substitution at the end.

What papers have hard vectors/Matrices. My integration is pretty good as a whole i think.

Sorry, how would I sketch a matrix's transformation? hate matrices, just bore me so much

Dunno mate I've only been revising for 2 days. I guess June 2013 R question 4 is pretty good because it's a matrix transformation of a plane.

Ah the R papers generating wonders of questions as normal. Ill have a look tmmrw after i finish recapping the content ha.

09 on wards there aren't any that are that hard. Pre 09 perhaps but haven't checked
9. Not strictly FP3 related but it made me laugh when I saw it at the bottom of the pdf for 1992's grade boundaries!

Those vectors are just j + k and i - k in column vector form
You want to use the relationship Ax = lambda(x) with A the matrix, x the eigenvector and lambda the eigenvalue
Ah thank you! I was looking at the matrix from the question rather than the normal identity one, makes a lot more sense now

monstrous?

Maybe I should be allowed to write a whole FP3 paper ...

fairly monstrous

In terms of A-Level standard.

would be more interesting to see a step paper from you

STEP has a very unique style which is very different to mine.

However this time next year there will be 26 SPECIAL IYGB papers which will offer very difficult questions across the standard C1-C4 syllabus.

Was about to teach my self to do 'step', holly molly, that would have been a nightmare. Pretty cool too see the types of questions though.

Some students have no choice if they need to do certain courses in certain universities.

Step is just questions on knowledge from a level. All you do is papers to practice and nothibg else really!

Understood, but sometimes you really do need some one to explain a concept to you, I don't have that because I'm teaching my self A levels.

Let me tell you ... best way to learn is "self taught". Only problem it takes a lot longer.

I would thumbs up your comment but TSR doesn't allow me too =[
