[Shadowless]

Where's 13d?

 

[_pikachu]

he skipped 13d
the one about blood concentration

 

[manscux]

Hi forgot 13d)

LOL

 

[Sindivyn]

Is Q7 right?

 

[VirtyDear]

can someone upload the paper?

Is Q7 right?

How is it not?

 

[Sindivyn]

How is it not?

Wait, I didn't see the second integration sign , makes sense now.

ZOMG....Just realised i said x=2 for horizontal asymptote not y=2 despite me getting the graph

hi guys for the question about displacement ... i think you had to say x =5 for displacement to be zero since it is pivoting around 5.. not zero.. terry lee wrote x=0 ... is this correct ???

I could get 69 if I'm really lucky (since I couldn't remember my answers and if I done it same way, but pretty sure it was no less than 63/70)

This is what im thinking , can anyone explain please ?

i think the units for Q13d) is meant to be hours

"x is the displacement"
"When is the displacement of the particle zero"
hence x=0

 

[RishBonjour]

+1 i agree

I did that question 2 ice in ze test. First x=5 and then x = 0
, note, when x = 0 , the cos(bla + blah) = -5 and hence x=0.

when x=5, you end up wrong.

x represents distance from the CENTRE of motion, not from origin, so it remains x=0.....thats how i understand!
