" 11.If "z=x+iy" where "x,y" are real,prove that "|x|+|y|<=sqrt(2)|z|

If z= x + iy, x, y real, prove that : |x|+|y| le sqrt2 |z| .

If z=x+iy , where x and y are real numbers and |x|+|y| lt= k|z| then k=.....

Let z=x+iy where x,y are real variable i=sqrt(-1). If |2z-1|=|z-2| ,then the point z describ es :

If x , y are real and x + iy=0 then

Let z=x+iy, where x and y are real. Thepoints (x,y) in the X-Y plane for which (z+i)/(z-i) is purely imaginary lie on

Let z=x+iy , where x and y are real. The points (x,y) in the xy-plane of which (z+1)/(z-1) is purely imaginary, lie on

If ((3)/(2)+ (sqrt(3))/(2))^(50)=3^(25)(x+iy) where x and y are real, then the ordered pair (x,y) is
