yes and i got A= 1/1800 and B = 1/1800 y does the mark scheme says A= 2 and B= 2 :S -

alright first of all i will use t instead of lamda for all steps in question 10(iii) they told u that the prependicular distance is equal from point p for both planes n and m and they gave u the formula to find the distance so we have x = 1+2t y = 1+t z= -1+2t plane m : x+2y-2z= 1 plane n... -
