This is easily repaired by applying the Edit>Derive Object command to the highlighted expression.  Edit the highlighted expression by selecting the Edit>Derive Object command. This brings a copy of the expression into the entry line with the cursor positioned at its left end, so the system is ready for editing.  Insert /4 after 5x^2, then end the input with (¢). The (¢) key performed a replacement of the old expression with the new one. There is no need to delete the old expression when using the Edit>Derive Object command. From each position you will see details that you can’t see from other positions. Based on this idea, mathematicians use a variety of different representations for mathematical objects. The fourth degree polynomial that you entered is displayed as an algebraic representation. Next you will produce a graphical representation, because this representation is particularly useful for obtaining information about the zeros. Since the major goal in this session is to properly document the mathematical work, . insert the text “First we try a graphic approach by plotting the polynomial in a 2D-plot window. ” “Plot” is a technical term. As such, it includes different aspects of drawing and graphical representation.
