Scroll to see replies

So ****ing pissed. Found the paper fine but I couldn't do the last part to que 9. Then I managed to work it out when i got home before checking on here but it's Obvs too ****ing late. Didn't register that "b/e" in the LN function included the function e. Kept thinking e was a constant, for **** sake.

guys if you don't cross out your answers then they have to mark whatever's there right? So if you showed an incorrect method and then a correct one but you didn't cross out the incorrect one then you'll still get the marks?

How marks do you think I have lost, if I've lost one do you think I could get an A* losing 6 marks???

Definitely, A* is probably going to be 68-69 max

It asked for simplest form; you could root that (as it's half a log) and get ln2.5.

i swear it said exact form not simplest form ?

Yeah I think it was that, I don't get how you solve it though

I subbed G into F

Got 28 / (x-2) = x + 1

Then ended up with X^2 - x - 30 = 0

which Im pretty sure is wrong and unsolvable

That's what I got!!

X^2 - X - 30 can be solved.. it factorises into (X-6)(X+5). Its what I got too leading to X = 6 and -5 ☺

For Q6, how many marks will I lose for using 0.5 as the gradient instead of -0.5? I differentiated correctly, got 2 as the gradient, and got the y value (16) at x=3 but the wrong equation for the normal

Its not unsolvable? (x-6)(x+5)?

What was 5a?
