Methods Exam 1: Discussion!

[Jon-_-]

Here are my preliminary solutions guys

I didn't check them, so I may have a few mistakes, but based on conversations with guys who did the exam they seem correct.

P.S. I have a blank copy of the exam too, so I'll upload that next.

Edit: I can now confirm my solutions are correct, except the graph is a bit revolting: I think it should go through (1,2) to get full marks.

You are my hero! My hero whi has pointed out that I just scraped past 50%... but a hero nonetheless!

Get pumped for tomorrow's exam everyone!

Think i got 38/40 and was a silly mistake from 40/40

Big big shame considering theres no way ill get A+ in exam 2, i needed to make the most of exam 1

[Jason12]

can anyone explain question 6 from paper 1? Even though its done already, I still don't get the worked solution.

Thank you so much for this!  Feel like I did pretty well... good luck everyone for tomorrow!!

Logex-logex^1/2=3
Logex-1/2logex=3
1/2logex=3
Logex=6
e^6=x
Does it make more sense like that?

[Jason12]

Logex-1/2logex=3
1/2logex=3
Does it make more sense like that?

sorry. I'm still unsure what happened between these two steps

[yoyoball]

sorry. I'm still unsure what happened between these two steps

Thats okay! Think of logex as one term like a and then if u take it out as a common its 1-1/2 which is 1/2

[keltingmeith]

Let ln(x)=a,

ln(x)-(1/2)ln(x)=3
a-(1/2)a=3
(1/2)a=3
(1/2)ln(x)=3

[Jason12]

thanks I get it now once you let a = loge^(x)

i deadset have lost 14+ marks on this exam, all my bloody effort throughout the year has gone down the drain. stuff this shit, dont even want to think about tomorrows exam at all

[Phanboy]

Well I barely passed 50%, if it is still possible, how much would I be looking to get for exam 2 if I'm trying to get a study score of 33+? --
Thanks

The first 7 or 8 questions seemed fairly normal to me. Questions 9 and 10 required a bit more deeper level thinking but judging by the suggested solutions I have full marked exam 1. Now all I need is a solid performance in exam 2 to back it up 

[LFC_Kero]

I got 80+ % on all my SACS, in a pretty strong cohort...
got 26-27/40 for exam 1
say I get 55/80 for exam 2

what study score am I looking at?

[Teagan_18]

Will I lose points because I didnt line up the equals (=) symbols

i.e..

blah blah  blah  = something else
something else = another thing and a bit
= x+ y

I was told to always line up the = signs but I was rushing and as far as I can remember, I didn't line them  up on at least two of the questions (exam brain kicked in where people tend to make silly mistakes)

[bobisnotmyname]

t'was a day for comical errors, indeed. Somehow in my stress I calculated the endpoint in 5.b as (-1, 2) instead of
(-1,4) and that means 5c is screwed as well =////////

And for q6 I rooted both sides instead of squaring both sides in the last step, ffs. I hope I get some mercy from the examiners.

rooting both side is and easy mistake, don't worry I did it to and I have no idea why, I guess the exam nerves got to me anyway
