I hear ya man.

Cool, I get it. Thanks vds. Can anybody do the second part?

Like usual I have a few questions I can't do. 1. Given that x = asin(nt+α), find v as a function of time (<--this part i can do). Find a, n and α if a>0, n>0, 0≤α<2pi and: a) the period is 6 seconds, and initially x=0 and v=5. 2. Particle moving in S.H.M. has period pi/2 seconds...

Best part when the Captain stabs the glass bottle in the guy's face continuously. Also when he is stitching up his face. I think you have to realise that the violence is not meaningless. It's supposed to for e.g. display just how violent a particular character is (in this case the captain).

I did the best slogs. Often accused of grabbing, but meh I didn't think so.

Shouldn't this be in the Extension 1 forum?

Was this for the pendulum prac (determining the value of acceleration due to gravity)?

I don't get the first half. This is my thinking: d/dx(1/2 v2) = -k 1/2 v2 = -kx + C v2 = -2kx + C Then x = 0, v = 100: and you get C = 10 000. I'm confused. So does that mean i have to leave it at 1/2 V2 = -kx + C.......and then sub? Tell me where i'm wrong. :p

Yeah i did have a feeling it was supposed to be memorized. I looked at Cambrdige and apparently int. Inx = xInx - x + c. Thanks you're right foram. Came across another question I couldn't do: A plane lands on a runway at 100m/s. It then brakes with a constant deceleration until it stops...

Hiya. Just lazing about doing some motion questions. Need to integrate the following: Int. 1 + logex dx Cheerios.

*slaps head* thanks smart 4U people. :rolleyes:

Thank you man. My log laws are a little rusty. Another problem I came across is the integration of 1/(cos2x) dx Just having a little trouble (this topic requires good knowledge of the other topics *sigh*). Cherios.

I'm doing motion questions and I need to express "x" in terms of "t". t = 0.5loge(2x-1) Some help?

hey guys I'm trying to figure out how to graph y = -4e-4t using a graphing program. I'm obviously doing something wrong because an error box appears. THanks

Yeah i am a bit confused about this too.

An essential investment for you DS. Get one now. Sell the games you already have and put it towards the R4.

Depends on what I'm reading or what I'm viewing.

Nub cake

EDIT: maybe i should shut my mouth. :)
