how did other ppl in your school find it?
and what do you think A* boundary is?

We all found it rerally easy from my school, I'm thinking 120-125 + for an A*

everyone I’ve spoken to seems to find it easy too. I agree with the other person about the boundaries - likely to be above 120 for an A*

does anyone remember what they got for the hyperbolic questions, the x coordinate, the equation of the line and the last integration question, the value for the rotation around the x axis?

The x coordinate for the hyperbolic was 2.89 to 3sf. The last integration was ln(3+2root3/3) and I don’t know what question you’re referring to with the rotation - are you talking about the volume of revolutions one?

the equation of the tangent to the hyperbolic was y = -2x+5

A* will be 120-123

The last question in section A was the only semi tricky question in the paper. The rest was pretty solid and you would pretty much check eveything on your calculator

What did people get for the improper Integral one?

I think it may have been -ln(2) but can't remember if that was a different question.

Yeah different question. It was the Integral of 1/(x-2)^(1/3) between 1 and 2

My answers from what i can remember:
Volumes of revs: pi^2/ 4
first angle question 34 degrees.
macluarin: n=181
vectors: S=6 angles 48 degrees?
Hyperbolics: y=-2x+5
Diffrential equations: y=3e^-2x+6e^-1x (Don't remember well might have been different values)
Last question. Maximum value was when t=126.something

I think I got that it was undefined but honestly that one had me stumped. Rest went okay, I think most of your answers were what I got, was a really nice paper imo
