<p><P>PROBLEM TO BE SOLVED: To provide an information processor capable of easily and immediately performing an operation of a numerical equation while improving a display function, an information processing program therefor, and a storage medium recording the information processing program. <P>SOLUTION: When a triangular function key is continuously pressed by a user, a formula corresponding to the triangular function continuously pressed and a drawing for understanding the formula are indicated on a display part 2. Since the formula of a triangular function and the drawing for understanding the formula are displayed on the display part 2 by the user's input operation by the use of the same triangular function key, the user can easily perform the operation of the triangular function, even if he/she forgets the formula of the triangular function, by referring to the formula and the drawing for understanding the formula indicated on the display part 2. Accordingly, the convenience is improved, and the time required for operation can be shortened. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
