Velocity=u, angle=●, horizontal component of u=ucos●, vertical component=usin●, we consider motion in horizontal direction s=x a=0, s=ut+1/2at2, x=ucos●t, t=x/ucos●..............now we consider motion in vertical direction a=-g, s=ut+1/2at2, s=usin●-1/2gt2 (t=x/ucos●) , s=usin●x/ucos●-1/2g (x2/u2sin2●), s=tan●x-1/2g(x2/u2sin2●) this is the expression for the path of projectile
