Two bodies are projected from the same point in the directions making an angle alpha_1 and beta_2 with horizontal and strike at the same point in the horizontal plane through a point of projection. If t_1 and t_2 are their time of flights. Then (t_1^2 - t_2^2)/(t_1^2 + t_2^2) =

Answer»

`(TAN (alpha_1 - alpha_2))/(tan (alpha_1 + alpha_2))`
`(SIN (alpha_1 + alpha_2))/(sin (alpha_1 - alpha_2))`
`(sin (alpha_1 - alpha_2))/(sin (alpha_1 + alpha_2))`
`(sin^2 (alpha_1 - alpha_2))/(sin^2 (alpha_1 + alpha_2))`
