<p>A geometrical graphic form (for example, a straight line 100) displayed on a geometrical window GW1 is selected, and a copy operation is carried out. When pasting is carried out for a formula window CW1, the selected geometrical form object is converted into the corresponding formula (for example, y = x), and the converted formula is displayed on the formula window CW1. A display region (for example, a specified region T1) of the formula is selected, and a copy operation is carried out. When pasting is carried out for the geometrical window GW1, a functional graph graphic form 102 is displayed on the geometrical window GW1 based on the selected formula.</p> |
