I defo got 56, I checked by doing the same formula to get U², so I'm pretty sure that's right. Also if U³ was above 100, the sequence would go down from 90 something to 70 something then back up to over 100, doesn't seem right to me!

What did we get for the 9th question values for costheta = 3/2 summit like that and the previous one of 180-45 and 360+45 which I got tan Inverse of (1) = 45

For the question with root(8x^3 + 1) being translated from root(x^3 + 1)

I got stretch in the x-direction by scale factor 1/2, because I thought if you are replacing the x with 2x you are stretching it by a scale factor of 1/2 not 2 :s-smilie:

Can someone explain please.

Original post by mike256

I think the question was actually the other way round: from sqrt(8x^3 + 1) to sqrt(x^3 + 1), so it was actually s.f. 2.

I got this question wrong; I put 1/2 :frown:

I put 1/2 too. :bawling:

What did people get for differentiation and the finding the normal equation page.

There was a question before it asked you to find dy/dx and i cant remember what it asked you to do so if anyone knows what question that was please say it.

my final normal equation went something like:

y=-1/60x+ (a fraction i cant remember)

Was pleased with log and trigonometrical equation I got x=-3 and 16,104,136. And I got p=6/5 eventually. I know I got the question about the obtuse angle wrong but should pick up a couple of marks and stretch scale factor 2 in x direction.pleased comparing my answers with people in my school I thought I was wrong!

What about the completing the square?

2(x+3/2)^2 + 0.5
min value = 0.5 anyone? :wink:

Guys please keep the answers coming, and it would help if you could remember the question number as well .

I am actively getting this mark scheme together so keep the answers coming
