  • Tracing and storing points of interest on a graphing calculator
    Patent number: 6867777
    Abstract: A graphing calculator (10) having an X=Editor with inequalities. The calculator (10) is programmed to provide an X=Editor which displays one or more “X=” to allow input of a vertical line inequality. The X=Editor allows the user to input an inequality symbol and a constant for each X, allows the user to select or deselect each X, and a graph function to graph each selected X on the X=Editor display.
    Type: Grant
    Filed: December 20, 2000
    Date of Patent: March 15, 2005
    Assignee: Texas Instruments Incorporated
    Inventors: Michelle A. Miller, Jian Zhang, Michael E. Hosea
  • Function graphing method with detection of discontinuities
    Patent number: 6704013
    Abstract: A function graphing method for detecting discontinuities. The method involves scanning piecewise linear segments of the function graph and detecting large changes in the angle between segments. When such changes in angle are found, a bisection routine is performed to determine whether a discontinuity exists between the end points of a segment.

  • Data-bidirectional spreadsheet
    Publication number: 20040044954
    Abstract: A spreadsheet software application that is integrated into a calculation environment, such that it is capable both of referencing prior definitions and results in the calculation environment and providing new definitions and results available for use in that environment outside the spreadsheet. Embodiments of the invention include the spreadsheet embedded in a compound document or in an application-based calculation environment on a computer display.
