The bid-rent curve has a negative slope because the activities balance the bid-rent with the cost of transportation to the point of attraction. Farther distances require greater transportation cost and thus reduce the amount of rent that can be paid. The bid-rent curve indicates why rents, and by inference land values, tend to be higher near central locations. Â« Better Business Bureau | big business Â».

Recursion in computer programming is exemplified when a function is defined in terms of simpler, often smaller versions of itself. The solution to the problem is then devised by combining the solutions obtained from the simpler versions of the problem.
Recursive definition. In mathematical logic and computer science, a recursive definition is used to define an object in terms of itself. A recursive definition of a function defines values of the functions for some inputs in terms of the values of the same function for other inputs. For example, the factorial function n! is defined by the rules This definition is valid for all n, because the recursion eventually reaches the base case of 0.
