GRAPHING CALCULATOR HAVING TOUCHSCREEN DISPLAY UNIT
First Claim
1. A graphing calculator comprising:
- a touchscreen display unit having a formula display area and a graph display area;
a formula input section configured to receive a calculation formula including a function, the calculation formula being input by a user;
a formula display control section configured to control the touchscreen display unit to display the calculation formula input to the formula input section in the formula display area;
a formula drag determining section configured to determine whether the calculation formula displayed in the formula display area is dragged to the graph display area according to a user operation input to the touchscreen display unit;
a function calculating section configured to perform a calculation corresponding to a type of the function included in the calculation formula when the formula drag determining section determines that the calculation formula is dragged to the graph display area;
a range setting section configured to set coordinate ranges to be used for generating a graph image corresponding to the calculation formula and a calculation result obtained by the function calculating section; and
a graph display control section configured to generate a graph image corresponding to the calculation formula and the calculation result according to the coordinate ranges set by the range setting section and to control the touchscreen display unit to display the graph image in the graph display area.
