A method for path tracing of mathematical plots on a digital device is provided that includes receiving at least one mathematical expression on the digital device, and tracing a path of a plot of the at least one mathematical expression on a display screen coupled to the digital device, wherein tracing the path comprises displaying the path sequentially point by point as a value of an independent variable of the at least one mathematical expression changes over a domain of the independent variable.

Path tracing of mathematical plots

A method and a digital device for evaluating a generalized rational function are provided in which the evaluation of the generalized rational function includes computing all discontinuities of the generalized rational function, determining, for each discontinuity, whether or not the discontinuity is a removable discontinuity, wherein the determining includes determining whether or not the generalized random function approaches a point near the discontinuity, and displaying each removable discontinuity. A method for evaluating a generalized rational function on a handheld graphing calculator is provided that includes determining whether or not the generalized rational function has at least one asymptote and displaying the at least one asymptote on a display screen when the generalized rational function has the at least one asymptote.

Computing and displaying asymptotes and removable discontinuities

A dynamic computational environment may create, in response to user input, a plurality of mathematical expressions. In the dynamic computational environment, a change made to any one of the plurality of mathematical expressions will be propagated to all of the mathematical expressions, such that each of the plurality of mathematical expressions affected by the change is updated.

Calculator with dynamic computation environment

A graphing calculator () having a user interface that allows the user to easily select mathematical objects from the history screen and incorporate those objects as inputs. The user interface preferably includes a sub-expression selection mode that allows the user to manipulate a selection box over the desired mathematical object.

Selection of mathematical objects from the history screen on a handheld device

A hand-held calculator programmed to teach mathematics in a manner which emulates traditional step-by-step teacher-student teaching methods and shows the important intermediate steps. Using linked lists, the method allows the use of selected data sets of problems and provides choices of mathematical operations, including transformations which are applicable or can operate on a selected problem. Importantly, the choices available to the student will not always lead to a solution or simplification of the problem. This allows the student to see the effect of an improper choice, as well as a proper choice.
