Let `S ={ (x, y) : x^2/9+y^2/4<=1}` and `T= {(x,y) : |x|<=3; |y|<=2}`

Let S = { (x, y |(x-3) ^(2) + (y + 42) ^(2) = 196} If A = min _((x,y) in S) sqrt (x ^(2) +y ^(2)) and B = max _((x,y) in S) sqrt (x ^(2) +y ^(2)), then |B-A| is equal to

Let f(x,y) = {(x,y): y^(2) le 4x,0 le x le lambda} and s(lambda) is area such that (S(lambda))/(S(4)) = (2)/(5) . Find the value of lambda .

Let R={x,y):x,y in R,x^(2)+y^(2) =(4)/(9)x^(2)} find the domain and range of R nn R'

Let f(x,y)={(x,y):y^(2)<=4x,0<=x<=lambda} and s(lambda) is area such that (S(lambda))/(S(4))=(2)/(5). Find the value of lambda

Evaluate : (viii) (3x + 4y) (3x -4y) (9x^2 + 16y^2)

Let us multiply with the help of identity . (x^2 + y^2) (x^4 - x^2y^2 + y^4)

Let X = {1, 2, 3, 4, 5, 6, 7, 8, 9} . Let R_1 be a relation in X given by R_1 = {(x, y) : x – y is divisible by 3} and R_2 be another relation on X given by R_2 = {(x, y): {x, y} sub {1, 4, 7} or {x, y} sub {2, 5, 8} or {(x, y} sub {3, 6, 9} . Show that R_1 = R_2 .
