We imagine this is the inclination that we want to launch at a slight problem though. There's a land in the way and you don't want to launch over land. If there's a problem you'd have to terminate the flight it could be very dangerous. So instead you launch at a different inclination. We call this a dog leg and there we are. You can see the track and the track is missing the land. Then what does a rocket do? It needs to reorientate or yaw in this case to the right. So now it has a component both parallel to the direction it's moving and perpendicular. You like a Y in an X. What happens? This allows it to follow the track and eventually end up on the right inclination.
