One big problem with using table lookups is creating the table in the first place. This is particularly true if there is a large number of entries in the table. Figuring out the data to place in the table, then laboriously entering the data, and, finally, checking that data to make sure it is valid is a very time-consum- ing and boring process. For many tables, there is no way around this process. For other tables, there is a better way-using the computer to generate the table for you. An example is probably the best way to describe this. Consider the following modification to the sine function: sin(x) × r = ((rx(1000 × sin x) )xe 0, 359]) 1000 This states that x is an integer in the range 0..359 and rmust be an integer.
