" If "u+iv=(2+i)/(z+3)" and "z=x+iy" then find "u,v

If u+iv=(2+i)/(z+3) and z=x+iy find u, v

Given that abs(z+i)=abs(z-i)=abs(z-1) and z=x+iy find number of pairs (x,y)

If u+iv=(3i)/(x+iy+2), then y in terms of u,v is

If z+sqrt(2)|z+1|+i=0 and z=x+iy then

If u + iv = (3i)/(x + iy + 2) , then y in terms of u , v is

If u=(2z+i)/(z-ki) where z=x+iy and k gt 0 Curve Re(u)+Im(u)= cuts y-axis at two point P and Q such that PQ=5 then value of k is

If U=(y)/(z)+(z)/(x), then find x(del u)/(del x)+y(del u)/(del y)+z(del u)/(del z) .

The locus of z=x+iy satisfying |(z-i)/(z+i)|=3 then find the radious of the circle

If a + ib = sqrt((u + iv)/(x + iy)) then the value of a^2 + b^2 is:
