Fig. 2-2 This relationship xy = 1 or y = l / x is best understood in the context of its graph. Numbers can be assigned to x, and y values calculated but note how the concept and language of limits make graphing so much easier.

One interface can inherit another. The syntax is the same as for inheriting classes. When a class implements an interface that inherits another interface, it must provide implementations for all the members defined within the interface inheritance chain. Following is an example:

Property public AuthenticationLevel AuthenticationLevel( get; set; } public virtual RequestCachePolicy CachePolicy { get; set; } public virtual string ConnectionGroupName { get; set; } public virtual long ContentLength { get; set; } public virtual string ContentType { get; set; } public virtual ICredentials Credentials { get; set; } public static RequestCachePolicy DefaultCachePolicy { get; set; } public static IWebProxy DefaultWebProxy { get; set; } public virtual WebHeaderCollection Headers{ get; set; } public TokenImpersonationLevel ImpersonationLevel { get; set; } public virtual string Method { get; set; } public virtual bool PreAuthenticate { get; set; }

at your friend s shop and he tells you that he ll have to grind the rubber down, rather than machine it like metal. After a few hours of experimentation, he hands you two rubber drive spindles. Now you have four spindles to mount both belts for a complete robot base, two rubber and two aluminum. After assembly, you find that the new drive spindles work pretty well. The rough ground surface of the spindle does a decent job of gripping the smooth rubber belt s surface. After trying the base out on the floor, you find that the turning is erratic and decide that you need a row of idler wheels to keep the entire length of each belt firmly on the floor. Your friend patiently machines for you 10 idler wheels, which you mount to a series of spring-loaded lever arms. Wow, this robot is beginning to be a bit complicated! After a few tries on your garage floor, you begin to notice that the teeth are wearing down. You smile at your creation and decide to put it away. It was a good learning experience.
