1.

If (cos alpha, cos beta) are new co-ordinates of P when the axes are translated to the point (1,1) then original co-ordinates of P are .

Answer»

`(2 COS^(2)"" (alpha)/(2), 2 cos^(2)""(beta)/(2))`
`(2 SIN^(2)"" (alpha)/(2), 2 sin^(2)""(beta)/(2))`
`(2 cos""(alpha)/(2), 2 cos""(beta)/(2))`
`(2 sin""(alpha)/(2), 2 sin""(beta)/(2))`
