1. FP2 June 2011 paper Q8 Edexcel
The particular solution to a differential equation is
x=(0.5 +(4t/3))exp(-3t) + (sin(3t))/18
On the graph of this particular solution the first turning point for T>30 is the point A. Find approximate values for the coordinates of A.

I have absolutely no idea how the markscheme does this - they dont really explain.
Any help would be really appreciated

Did that question 2 days ago. Got it after 5 minutes of thought. They should set questions like that more often imo, but 2 marks is a bit stingy.

Looking forward to both FP2 and FP3. 90+ in both if all goes well. I think edexcel f. maths is overrated - revising more for STEP III tbh. I know, it's crazy to do 3 when you can meet an offer by doing 1 but I like a challenge.

Its quite a challenging question, btw.

In FP3 i can go blank at a difficult locus question, that is the only hard thing in it.

What do you need in STEP?

It's Warwick uni so grade 1, but the exam is next Wednesday so I've got quite a bit of time yet.

Definitely agree with that. It won't lose you many marks though as ost of them are 2-3 marks.

How was STEP 1?

I'm doing STEP II (had it today) and STEP III.

Both me and my f.maths teacher agreed that doing II and III would prepare me better for a tough uni course.

It's actually good that they are both in the afternoon. Don't know how I could walk into such a testing and long exam first thing.

Got a clash on Monday. FP3 with M5

How was your M4?

I have heard it was very difficult!

Yes it was on the tough side. Pretty sure I got around 60 marks which should be an A fairly comfortably.

Timing is a huge issue when it comes to M3, 4 and 5.
