Note that , and by the chain rule, . Note that the set of possible velocity vectors forms a vector space. If and are two paths through the origin, then so is and the velocity vector of this path is . Similarly, if is a scalar, then the path has velocity vector . It makes sense to distinguish the velocity vectors at different points. In physics, the set of all velocity vectors gives all possible combinations of position and momentum, and is called phase space.
Often ribs are boiled or oven-steamed before grilling to help tenderize the meat. To oven-steam ribs, place ribs in a large baking pan, fill with about 1 inch of water, cover with aluminum foil and bake for about 50 minutes in a 350-degree oven. The recipe here includes instructions on how to boil ribs before grilling.
Part 2 Cooking the Ribs. Preheat the oven or grill. Beef ribs need to be cooked low and slow, and you can do it either in the oven or on the grill. Preheat to 225 degrees Fahrenheit (107 degrees Celsius). If you're cooking on the grill, you can smoke the ribs by adding applewood chips to the coals.
