    OMGG exactlyyy, first page was easy and complex number is something new, the sketch was fine, and vector first part is easy only second part where they gave angle 60 degrees, then trigonometric subs, especially differential I couldn't eliminate the logarithmic

    it's actually june 2010 paper 32 qp 9. (ii) 6 marks where they ask find the length of AB, given the line equation that meet the plane p at A and plane q at B so that AB direction vector would just be the direction vector given in the line eq. so instead I just find |AB| magnitude and got the...

    Will we get full marks if we got our final answer correct but very short working? It is 6 marks but I got correct? Or you have to do the long way? Like if Find length AB given the line r=something and meets at plane p at A and plane q at B. Find AB length (June 2010 paper 32)

    for 3 c ii provide the same wave exactly identical but decreasing amplitude 5 b draw 4 capacitors, 2 and 2 in parallel for 6 a parallel because then you would want force to be perpendicular to the magnetic field and with current use left hand rule 6 b i torque is Fd ofcourse the distance...

    I think from R to P is because the whole cycle should get the sum equals zero, but I don't know why Q to R is zero, It's not in any book about this PV graphs =/

    differentiate both sides, one by quotient and the other half by implicit because it contains y^2

    Oh yes, I got the answer, first do what I said and then get dy/dx as subject after implicit differentiation, then simplify it, you get to the point where you have to multiply by (1+x)^(1/2) / (1+x)^(1/2) then you will see difference of two squares, there bingo good luck
