The Dumbest mistake u've ever made in a Maths Exam (2 Viewers)

[aussiechick007]

weeeell.... i wrote the area of a triangle = a x b , that was pretty silly of me!

 

[karnage]

There was a question that said differentiate this, but for some reason i differentiated the first bit and integrated the second bit

Lost a mark, would have gotten full marks!

Would have been ok if i got the harder questions wrong but cmon

 

[dillay]

Picking maths was my dumbest mistake ever D:

my maths teacher hates me for some reason >_>"

 

[a.Limjoco]

lol, in the heat of the half yearlies i proved that 4 = 2

 

[vds700]

my friend did 7^2 = 14

lololol

so im not the only one. Lol!!!

 

[hollyy.]

in the half-yearlies - ap question

a+12d=1
a=7
therefore
7+12d=1
12d=-6
d=-2...............

wtf was i thinking...stupid brain.

+ i always integrate instead of differentiating and vis versa

well, my last maths test i managed to decide that 1x1=2, however that whole test was a testament to my stupidity...my overall result was 18% lolz

 

[conics2008]

one of the qusetion said ..

use the results sin^2 x = 1/2( 1+ cos2x) to show that sin^4 (x) = something i forget

I knew what i was doing i wrote my answer like this

WHEN you expand cos( 2x + 2x ) you get sin^4 (x) = something


never ever do this guys =)

losing a mark for writing stationary pt instead of turning pt - gay

 

[CRANK-SHAFT]

2 x 7 = 9.

- (a + b) = -a + b

HAHA these sorts of mistakes are getting common for me LAWL...

lastweek in the HY exams for EXT1 maths I had an integration question and lost marks coz i wrote 2x instead of 2x+c

I was friggin cut HAHA

 

[ahhliss]

*sigh* So many times I've either copied the answer wrong from my calculator or pressed the wrong buttons in the first place. My working is correct but the answer is weird. I usually lose one mark for that >.<"

 

[ronnknee]

Shit, I can't take this anymore. Reading this thread is gonna change my concept of maths :|

 

[rosypink]

i dont even wanna recall back to all my stupid mistakes - just makes me want to kick myself...i hate it when i lose such easy marks - then im only like 2 marks away from the kid who came first arghhh..pisses me off =[ when i could have been the one topping the exam !!!!!

 

[sonnylongbottom]

1 x 1 x 1 = 3
well it was a long exam and i was stressed so yea brain explosion

 

[hollyy.]

I didn't do this but my maths teacher was marking last year's HSC and got this:

sec x/C = sex

lol.

ha cause the c's cancel lol.

First Extension Maths assessment this year, question 1, (2x-1)^3...began expanding using pascal's triangle (not a fan of formula) went 1 3 3 1
then cubed all the x's and not the 2...ended up with 2x^3-6x^2+6x-1....
same exam question was 3sec^2x = 3 + tanx, stupid me replaced sec^2x with 1-tan^2x rather than 1 + tan^2x...came first nonetheless =)

 

[Zrap]

1+1= Window

 

[conics2008]

rubics cubbing in exam!


jst kidding, hey you know what PS stands for ?

ouch. that's terrible.
I heard that your exam was really hard though. Congrats on the mark.

2m+3m=6m o.0

Also in the same assessment for integration by substitution, I wrote x+1 on the first line, but u=x-1, so x=u+1. In the second line I replaced x+1 with u+2. On the third line, I must have looked back to the first line because I wrote u+1 I got the rest of the question but lost 1 mark because of that part >.<"
