listen find the equation of the line joining A n B.....p must lie on the same side of origin......then p n A lie on the same side of the X-axis(considering A as(0,root3/2)......then again p n B lie on the same side of Y-axis........substitute n get the answer..............

c first calc the equns of all the 3 lines then put
the value of the coord of the pt. opp to that line in the eqn. n check the value (that is wether it is +ve or -ve)
then put coord of p in the same eqn
and then form the inequality
repeat it fr all the other eqns.
u will get the ans.
