Here is the 2 unit paper.

Definitely a harder paper than 2014 and 2015!

What'd people get for 16 b ii?

 

[ml125]

What'd people get for 16 b ii?

10≤ y < 200 iirc

[InteGrand]

10≤ y < 200 iirc

Yeah, that's right.

 

[Dragon9000]

Kill me. I got 0 < y < 200

 

[MilkyCat_]

What was 16 b iv?

 

[MilkyCat_]

Also 14 d?

 

[the_matrix]

what was value of h for 15. C iii)

Tell me it is h = xy

 

[trecex1]

I got h=y/x

Overall easier than previous years, pretty confident I got 99-100

 

[the_matrix]

((((( gg fmd

10≤ y < 200 iirc

Tfw forgot t >= 0 and got 0 < y < 200 and got period of tan3x as 2pi/3 rip.

 

[pikachu975]

What was 16 b iv?

I got 100 but I think my method was not enough for 2/2 marks.

Also 14 d?

5

Yep it's y = 100. All it amounts to is that the parabola y(200 - y) (which is concave down obviously since the leading coefficient is negative) has its vertex (hence maximum) at y = 100 (midpoint of the roots).

Is this also correct? https://postimg.org/image/t452ixfzz/ Since like dt/dy is the reciprocal of dy/dt

For 15 a I used wrong equation for volume of a sphere rip

 

[severus snake]

lmao so easy gg

yeeeeeeaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhh booooooooooooooiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

 

[RenegadeMx]

lel easy test considering ur given the formulas nowadays

It wasn't even a sphere though, did you use the sphere formula
