I am unable to proceed on how to do the steps, if someone can guide me , im not looking for full solution but some guidance.
Question : Denote by a,b the lines with the Cartesian equations y=0,x=0 respectively, and i=[ 1 0 ],j=[ 0 1 ] (a) Find the functions f(x,y) and g(x,y) such that γ a,i (x,y)=(f(x,y),g(x,y)) . (b) If γ a,i (P)=Q , show that the midpoint of the segment PQ belongs to a . (c) What is the isometry γ a,i γ b,j
