    Guys need urgent help here. 9702/52/M/J/13 Question 2 Part d(i) And therefore (e) My gradient is: 44.9 x 10^-3 And hence my E becomes 3.56 And my V, in (e) is therefore 55.6 +/- 5 According to the marking scheme, I went wrong at part (d)(i), E they say, is my answer x 10^4 Someone please...

    Can someone please help me with this one? I know how these questions go but this one seems abit tricky. They said A graph is plotted of V/E on the y-axis against 1/R on the x-axis. Express the gradient in terms of F. Now if the gradient is y/x I get Gradient = VR/E Now in terms of F From...

    Can someone solve this? I solved part (i) easily and part (ii) doesn't depend on part (i) so let it go. Now in part (ii) I was able to draw the circle with centre i and radius 1. I just wasn't able to draw a locus with angle 3/4 pi to the real axis. Can someone help me draw the locus and...

    Yes I know that. But Im not using angle BOC im using BAC. Using BAC to find the area of so sector includes the area of the segments above OB and OC, but using angle BOC includes the area of the segments below AC and AB which is fine but that's not the flawless answer.

    Can someone help me with this question? The question is as follows: Basically I found the area of the ABC sector and added the segments below the AB and AC lines. This is how I went: AB = 2r.cos(theta) AngleBAC = 2(theta) A of sector ABC = 1/2 x (AB)^2 x (2theta) = 1/2 x (4r^2.cos^2theta.) x...

    I dont understand the last step, the one right before the final answer.. How does the denominator finalize to become 1? I know that the numerator is the answer we're trying to reach, okay. But the denominator should be 1, now how does 1 + (tant) (tan 1/4pi) equate to 1? (tan 1/4pi) is equal to...

    The e^ix +1 = 0 (Euler's identity) is actually derived from euler's formula ye^ix = y(cosx + isinx). Thanks alot for simplification.

    Complex numbers question. I would like some help with understanding how to interpret these three points and place them on a diagram, and perhaps then calculating the area of the thus formed triangle. Thanks in advance.

    Yeah thanks your answer sort of makes sense after the diagram. Sadly <ZaqZainab> just quoted what the examiner report said which was not so clear. Its actually as you stated, area x distance traveled in one second x density. And then into velocity to achieve rate of change of momentum...
