Edexcel FP3 - 27th June, 2016

The guy they hired to do the solutions got drunk that night.

Unpopular opinion: Chapter 2 mixed exercises is quite nice...

they're doable after the first 3

FP3 is probably the worst module I've ever done. None of the content seems hard, but I've done exam questions and they just leave me so confused (literally any topic). Are there any websites that explain the solid parts of FP3 (namely loci of points associated with certain graphs and vectors).

Thank you, last time I checked that website FP3 wasn't finished.

Apparently question 8 last year was hard (the last question).

My friend didn't answer the last part in the exam last year :0.

yea it got finished off quite recently, just in time too

It hasn't been finished. There's nothing on matrices, hyperbolas and it's missing a huge chunk of integration.

I can't understand what the last part of this question wants me to do, would anyone be able to explain it to me?

Thanks

I'm not sure what the "cosines" mean but as Eric, said - the unit vector in the direction OF.

If you have a normalised vector, the cosine of the angle between it and each of i, j, and k are the components of the vector, as can be seen by taking the dot products.

Ah, thanks!
