In the figure, C and D are mid points of OA and AB respectively. OD and BC intersect at E. OE : ED =r :1 and BE : EC =m :1. (a) Find the coordinates of C and D. (b) Prove that the coordinates of E A (2a, 26) 4ra rb `1+r' 1+r' are (c) Prove that the coordinates of E в (ба, 0) (6+ m)а тb are OE: ED =r: 1; 1+m 1+m BE: EC = m: 1 (d) Hence find the values of r and m.
