We now have the differential equations of motion but need initial conditions to solve them.
Let us examine the projectile at the instant of muzzle exit without worrying about how it

the initial tube angle in azimuth and elevation as θ
0
and ϕ
0
, respectively. Then our initial
velocity vector can be dened as
