Ok so v can start discussion now for p1 ... I wrote under root pi as the irrational number, is dis correct?

on what point did the girl's graph end in that kinematics ques?

on what point did the girl's graph end in that kinematics ques?

it was to be at 13.55
though I didn't count the first ten and drew it only till 45 :'( how was her grAph's shape btw?

Dun worry u vil get 1 mark still there was a horizontal line at 18 first, line then dropped straight down to zero. Progressed on the x-axis, then rised straight till 20 from where there was another horizontal line

Hey can ull please tell me how to calculate the shear and strech factor?

FE is simple FA + AE. AB = 4AF, so AB = 4p. AC = 2q. Now BC = BA+AC. Cuming to b(i), BD= k x (ans of aii). AB was 4p, so FB=4p-p=3p. Now FB+BD=FD. b(ii), apply the concept of parallel vectors here, n then compare the coeficients

Lets suppose C is object and c is image. Stretch factor = distance of c from invariant line/distance of C from invariant line. Shear factor = distance between C and c/distance of C from invariant line

FD is 'x' times of FE. Eq is like FD='x'FE. Put ur ans to FE n FD in the respective places. Once done, compare the coefficients on both sides of eq. This vil give u value of 'x' from which k can b found
