IF `A={x//x in N, x lt6}` and `B={x:x in N, 3 lt x lt 8}` then show that A-B`ne` B-A with the help of Venn diagram.

IF A={x:x in N, x lt 10 }, B={x:x is a prime number and x lt 10 }, then show that A-B ne B-A with the help of Venn-diagram.

IF A= {x :x in N and x lt20} and B= {x :x in N and x le 5} , then write the set A-B in the Set-Builder form.

A = {x : x in R, x ge 2}, B = {x : x in R , x lt 4} " then " A cap B =

IF 4lt x lt 8 then the value of - 7x^2+8x -9 is

A={x:x is a perfect square, x lt 50, x in N} B={x:x =8m+1, where m in W, x lt 50, x in N} Find A cap B and display it with Venn diagram.

B={ x//x in N and x lt 1000 } is a …………..set.

If x in (0, pi//2) then show that 2x//pi lt sin x lt x .

A = {x : x in N, and x is a factor of 30}, B = {x : x in N and x is a prime factor of 30}. Draw Venn diagram for AuuB .

If A = {x : x is a prime and x lt 10 }, B = {x : x is a factor of 6}, then find AnnB , AuuB and A - B.
