A variable line is drawn through the origin O. Two points A and B same side of O are taken on the line such thatOA=1 and OB=2 unit. . Through points A and B two lines are drawn making equal angle alphawith the line AB. Then the locus of the point of intersection of the lines, is:

Answer»

`X^(2)+y^(2)=(9+tan^(2)ALPHA)/(4)`
`x^(2)+y^(2)=(9-tan^(2)alpha)/(4)`
`x^(2)+y^(2)=(9+tan^(2)alpha)/(2)`
`x^(2)+y^(2)=(9+2tan^(2)alpha)/(4)`
