    HOW WAS MATHS PAPER 2?????

    Actually the first part was a rotation of 180 degrees about midpoint of line RS(centre) and the last part was a two way stretch with stretch factors 2 and 3 for stretch parallel to x axis and y axis respectively...

    yep..my guess too... but still those who have put parallelogram may be awarded their mark... since the fact that E and A was collinear was mentioned in the next part...

    HOW WAS MATHS PAPER 2?????

    and how ur question on mensuration?? i managed to answer all parts of transformation and i hope they are correct...so i opted for transformation i guess the majority has opted for mensuration rather than transformation,rite?

    PHYSICS PAPER 4 (ATP) DISSCUSSION

    but for (4) i've written the opposite of ur answer... u've said time decreases...and i've said that time increases and i've mentioned that the rule may hardly rotate or does not rotate smoothly when d is less than 15cm..

    MATHEMATICS PAPER 1 Discussion

    it was actually a trapezium...since some points were said to be collinear... but if they do not take the next part of the question into consideration...then both parallelogram and trapezium are correct...

    PHYSICS PAPER 4 (ATP) DISSCUSSION

    for (3) u shud show that the product dT is a constant... and for (4) actually when distance increases time decreases so if u decrease the distance d so time will obviously increase...the rule B would not have rotated smoothly and reproducibly or u could say it would take too long for it to rotate...

    RHS=tan x - 1/ tan x + 1 = (sin x/cos x ) - 1 /(sin x/cos x) + 1 {since tan x = sin x/cos x) = (sin x - cos x)/cos x / (sin x + cos x)/ cos x { cos x as a common denominator} = (sin x - cos x) / cos x * cos x /(sin x + cos x) { cos x is cancelled out} = (sin x - cos x) / (sin x + cos x)...
