The above discovery goes right to the heart of the matter as to what exactly the n-body problem is physically: as Newton realized, it is not sufficient to just specify the initial position and velocity, or three orbital positions either, to determine a planet's true orbit: the gravitational interactive forces have to be known too. In programming, a function is a sequence of instructions that performs a specific task. {\displaystyle y_{n+1}=y_{n}+hf(t_{n},y_{n})} The planetary problem is the n-body problem in the case that one of the masses is much larger than all the others. 3 This also shows up in the Butcher tableau: the coefficient matrix Even more phenomena are possible.
