Circle (x 1)^2 (y 2)^2 = r^2 & x^2 y^2 - 4x - 4y 4 = 0 Cuts each other at two different points then value of r is

If r_(1), r_(2) " and " r_(3) are the radii of the circle x^(2) + y^(2) - 4x + 6y = 5 , x^(2) + y^(2) + 6x - 4y = 3 " and " x^(2) + y^(2) - 2x + 4y = 8

If x = r cos theta and y = r sin theta, prove that (del ^ (2) r) / (del x ^ (2)) + (del ^ (2) r) / (del y ^ (2)) = (1) / (r) [((del r) / (del x)) ^ (2) + ((del r) / (del y)) ^ (2)]

If f(x+y) = f(x) + f(y) + |x|y+xy^(2),AA x, y in R and f'(0) = 0 , then

If P=7x^2+5xy-9y^2 ,\ Q=4y^2-3x^2-6x y\ and R=-4x^2+x y+5y^2,\ s how\ t h a t\ P+Q+R=0.

Define relations R_(1) and R_(2) on set A = [2,3,5,7,10] as x R_(1) y is 2x=(y - 1) and x R_(2) y if x + y = 10, then the relation R given by R = R_(1) cap R_(2) is

If R ={(x,y): x,y in Z , x^2 +y^2 =64} then , write R in the roaster form

If R={(x,y): x,y in W, x ^(2)+y^(2)=25} , then find the domain and range or R.

If the length of the chord of the circle , x^2 + y^2 = r^2 (r gt 0) along the line , y - 2x = 3 is r , then r^2 is equal to
