  1. Draw a diagram of circle with origin as centre and Mark all the points on x and y axis
  2. All points are (1,0) (0,1) (-1,0)(0,-1)
  3. As we know min distance between two points will be a line joining (1,0) (2,0) and (-2,0)
Length of tangent will be \sqrt{}S(-2,0) which will when doubled give the exact length where S= x2+y2=1 
2* \sqrt{}\frac{}{}(-2)2 +0 -1 = 2\sqrt{}3
