when D will be 0 then in the first input to the lower nand gate will be 1 and the first input to the upper nand gate will be 0 If clock (CLK) = 1 then in the upper Nand gate 0 NAND 1 will be 1 and in the lower nand gate 1 NAND 1 will be 0. now In the Second upper NAND gate 1 will go as the...

Tell if this Argument is valid (Propositional Logic)? P = If a man is bachelor he is unhappy Q= if a man is unhappy he dies young C = so the conclusion will be Bachelors die young is his right ? This we have to write this in this form is this correct ----> means implies Q ---> Q Q...

Thanks both of you :)

I don't understand the logic behind standard equation or Expressions for various Functions. For example: Constant Function: so from this pic you can represent constant function is f(x) = y ..when every x value gives the same y value (7 in the above case) constant function is written as F(x) =...

Thanks ...

A = {1,2,3} B= {a,b,c} c = {x,y,z} R = {(1,a) (2,c) (3,a) (3,c)} S = {(b,x) (b,z) (c,y)} Find RoS (composition of relation)my solution was this: (2,c) belongs to R and (c,y) belongs to S so (2,y) belongs to RoS (3,c) belongs to R and (c,y) belongs to S so (3,y) belongs to Ros RoS={(2,y) 3,y}...

Let R be a relation on set A={1,2,3,4} R = {(1,1) (1,2) (1,3) (1,4) (2,2) (2,4) (3,3) (3,4) (4,4)} Construct a matrix of R I don't know how to solve matrix can you tell me how to construct a matrix with this Relation
