1. ## Please Solve this question of Discrete mathematics

Let D and S be relations on A = {0, 1, 2, 3}.
• D = {(a, b) | b = 3a+1 mod 4}
• S = {(a, b) | b < a+1}

Then find values of S°D by writing all the intermediate steps

thank you very much dear sir. I am much confused I can not find my result so Please give the answer of S°D=???????????????

4. ## Re: Please Solve this question of Discrete mathematics

I find S°D={(0,0),(0,1),(1,0),(2,0),(2,1),(2,2),(2,3),(3, 0),(3,1),(3,2)}. is am I correct????? or Not. If not then please find S°D=????????????
