1.	Two bodies are projected from the same point in the directions making an angle alpha_1 and alpha_2 with horizontal and strike at the same point in the horizontal plane through a point of projection. If t_1 and t_2are 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))` ANSWER :C
