Curve display control device, curve display control method and curve display control program

摘要

A curve display control device includes a processor. The processor operations include: storing a functional equation in a memory; Displaying a curve corresponding to the stored function equation in a coordinate system of a display, indicating a plurality of points on the displayed curve in response to actions of a user; Obtaining a slope value of a tangent to the displayed curve at each coordinate corresponding to each of the plurality of specified points; Plotting the corresponding slope values as a value of a coordinate in the coordinate system; Performing a regression calculation based on the plurality of plotted points to obtain a regression function equation of a curve corresponding to the plurality of plotted points; and displaying on the display a curve corresponding to the regression function equation obtained by the regression calculation.
