True or False
If `A xxB = {(a,x),(a,y),(b,x),(b,y)}`, then = {A,b} and B = {x,y}.

If AxxB={(a,x),(a,y),(b,x),(b,y)} . Find A and B

If A xx B = {(a, x).(a , y). (b, x), (b, y)}. Find A and B.

If y= f(x) =(ax-b)/(bx-a) , prove that f(y) =x.

If X= { a, b, c, d } and Y ={f, b, d, g}, find:- X-Y

If X= { a, b, c, d } and Y ={f, b, d, g}, find:- Y-X

If the sets A and B are defined are defined as A={(x,y):y=e^x, x in R},B={(x,y):y=x, x in R} then a. B sub A b. A sub B c. A nn B = phi d. A uu B

If A(x_(1), y_(1)), B(x_(2), y_(2)) and C (x_(3), y_(3)) are the vertices of a Delta ABC and (x, y) be a point on the internal bisector of angle A, then prove that b|(x,y,1),(x_(1),y_(1),1),(x_(2),y_(2),1)|+c|(x,y,1),(x_(1),y_(1),1),(x_(3),y_(3),1)|=0 where, AC = b and AB = c.

If X= { a, b, c, d } and Y ={f, b, d, g}, find:- X nn Y
