Abstract
A system and method for graphing mathematical features of a given function within an optimum viewing window. The system and method can also highlight the mathematical features. Further, for example, the system and method can determine the type of a function and the various behaviors of the function, and highlight curve segments of concavity, increase/decrease, and where the function is constant.
Claims24
A system for creating a graph of a mathematical function comprising:
- a user entry subsystem receiving the mathematical function;
- a features subsystem determining function-specific mathematical features of the mathematical function;
- a window subsystem automatically creating function-dependent maximum and minimum x- and y-coordinates of a window to include said function-specific mathematical features associated with the mathematical function, said function-dependent maximum and minimum x- and y-coordinates defining the window containing the mathematical function without the need for said function-dependent maximum and minimum x- and y-coordinates being independently input, and said window subsystem further displaying said graph of the mathematical function in said window,
- wherein said features subsystem automatically performs a feature analysis while performing said step of determining function-specific mathematical features of the mathematical function and providing said function-specific mathematical features to said window subsystem;
- and
- wherein said window subsystem provides said function-specific mathematical features in said window.
