Electronic apparatus, information processing method, and recording medium

An electronic apparatus comprising:

• a display;
• and
• a processor which:
• displays, in a screen of the display, a graph frame, a mathematical expression input frame, and a line visually connecting the mathematical expression input frame and the graph frame, in response to a user operation;
• sends, to outside of the electronic apparatus, first mathematical expression data on a first mathematical expression input in the mathematical expression input frame by a user operation;
• receives, as a result of an arithmetic operation executed based on the first mathematical expression data sent to the outside of the electronic apparatus, graph data visualizing the first mathematical expression;
• displays a graph based on the graph data in the graph frame;
• displays, in the screen, (i) at least one coordinate display frame including coordinates of at least one point on the graph specified by a user operation, and coordinate icons symbolizing coordinate values of the coordinates of the at least one point, and (ii) a line visually connecting the at least one coordinate display frame and the graph frame;
• displays an arithmetic setting frame in the screen;
• sends, to the outside of the electronic apparatus, second mathematical expression data on a second mathematical expression formed in the arithmetic setting frame by at least a part of the coordinate icons being selected by a user operation;
• receives, as a result of an arithmetic operation executed based on the second mathematical expression data sent to the outside of the electronic apparatus, arithmetic result data of the second mathematical expression;
• and
• displays an arithmetic result of the second mathematical expression based on the arithmetic result data of the second mathematical expression in the screen.

A non-transitory computer-readable recording medium storing a program of a system, wherein the program is configured to allow a computer to:

• display, in a screen of a display of an electronic apparatus, a graph frame, a mathematical expression input frame, and a line visually connecting the mathematical expression input frame and the graph frame, in response to a user operation;
• send, to outside of the electronic apparatus, first mathematical expression data on a first mathematical expression input in the mathematical expression input frame by a user operation;
• execute an arithmetic operation based on the first mathematical expression data sent from the electronic apparatus, and send, to the electronic apparatus, graph data visualizing the first mathematical expression as a result of the arithmetic operation based on the first mathematical expression data;
• display a graph based on the graph data in the graph frame;
• display, in the screen, (i) at least one coordinate display frame including coordinates of at least one point on the graph specified by a user operation, and coordinate icons symbolizing coordinate values of the coordinates of the at least one point, and (ii) a line visually connecting the at least one coordinate display frame and the graph frame;
• display an arithmetic setting frame in the screen;
• send, to the outside of the electronic apparatus, second mathematical expression data on a second mathematical expression formed in the arithmetic setting frame by at least a part of the coordinate icons being selected by a user operation;
• execute an arithmetic operation based on the second mathematical expression data sent from the electronic apparatus, and send, to the electronic apparatus, arithmetic result data of the second mathematical expression as a result of the arithmetic operation based on the second mathematical expression data;
• and
• display an arithmetic result of the second mathematical expression based on the arithmetic result data of the second mathematical expression in the screen.
