Let f(x)={(e^({x^(2)})-1,xgt1),((sinx-tanx+cosx-1)/(2x^(2)+In(2+x)+tanx),xlt0),(0,x=0):} where { } represents fractional part function. Suppose lines L_(1) andL_(2) represent tangent and normasl to curve y=f(x) at x=0. Consider the family of circles touching both the lines L_(1) and L_(2) If centres of circles belonging to family having equal radii r joined, the area of figure formed is
