Course Introduction:1. To edit a number with a root sign, open the text tool, select [Text Tool], drag a text box on the drawing board, in the text input state, click the [Symbol Panel] button below, and then select the root in the pop-up template. number template, so that numbers with root signs can be typed. 2. Draw the function image with radical sign. Step 1: Open the geometric sketchpad and select the [New Function] option under the [Data] menu. Step 2: The New Function dialog box pops up. Find sqrt under the equation drop-down menu. For example, the function y=√x is sqrt(x). Step 3: After clicking [OK], the function expression will appear in the upper left corner of the work area; right-click the function expression and select [Draw Function] to draw the function image with the root sign.
