If (a,a^2)falls inside the angle made by the line y=x/2,x>0 and y=3x,x>0 then a belongs to:

Arun · Answer

y = x/2 ; m1 = tan -1 (1/2) y = 3x ; m2 = tan -1 (3) Since the point (a,a 2 ) lies between the angle auntanded by lines L1 and L2 at origin qill lie between m1 and m2. Hence m = a^2 -0/ a- 0 = a tan -1 (1/2) -1 (3)
