How was Additional Mathematics Paper 1?

[random]

how much you get for mu thing?

 

[Skyrior]

mu?????? was that or? i chose either...

 

[jsdeo]

oh no...

Someone else got the same answer as you, so I'm probably wrong

 

[Skyrior]

we shouldn't be discussing actually....wait 24 hours ....

 

[bumblebee]

i doubt i could pass over 75, i got stuck on dy/dx *****************************************...

skrior dont worry, for the area i got 156 too, and so did my whole class, good luck everyone!

 

[jsdeo]

we shouldn't be discussing actually....wait 24 hours ....

yeah... anyway I recalculated and your answer for the area of the triangle was right

 

[Skyrior]

did anyone chose either, none of my classmates did....what was the relative velocity, was it (51i + 40j)?

i did it...and no i didnt get that. omg add maths has been my strongest subject and now i think im gonna kill it ):

I know, same here! It's always been my best subject but I'm thinking now it's likely to be my worst grade... probably due to the significantly higher GTs compared to other subjects

 

[Skyrior]

(variant 2) did you get 51 degrees for the direction? i got thirty-something though....but the pro genius in my class (he's the only one that chose either with me) said it's 51...

 

[Spidey21]

no

I know, same here! It's always been my best subject but I'm thinking now it's likely to be my worst grade... probably due to the significantly higher GTs compared to other subjects

pe it wont have that high GT cuz only a few around had a paper of wonder..rest are worried..

 

[bumblebee]

i took OR cuz i suckkkkkkkkkk at vectors with diagrams of general examples

 

[kim anika]

i hav doubt
e^y=lny
is it correct

 

[bumblebee]

nope, if you are doing differenciation, it will still be e^y

 

[Skyrior]

How do you differentiate:

(2 - 5 tan 2y) / 6x

(It's different from the exam one, well, but i want to know how to do that question)

 

[fcbayernmunchen]

Well, At least Paper 2's going to be void of Relative Velocity and Vector stuff! And would have possibilities of a good score as you'd have trigonometry, matrices, sets, binomial theorem, BLAH!
I guess I'm gonna nail this one to overcome the 10-15 marks I doubt in my Paper 1 score :[

 

[kim anika]

nope, if you are doing differenciation, it will still be e^y

ok thnx.....plz pray

 

[kim anika]

for differentiation of the tan x thing:

4 - tan 2x
-----------
5x

...................who can do it?

can u rite ur question more clearly

 

[Skyrior]

can u rite ur question more clearly

you did the 12 variant right? the 2nd differentiation question:

********************

dy/dx = ?

In Shah Allah u will nail...nw pray for me so dat i can nail in p1
