The following project will help a user become more familiar with graphing polar functions, sketching geometry parts, using text, color settings, and more.
Create a flower (using polar functions) with the message "Happy Valentine's Day!"
Step-by-Step Instructions and Illustrations:
1: New Document
2: Add Graphs
Make a Flower
3: Graph entry/edit
"Trig" (select Cos)

(equation text disappears)
Change Color and Thickness
Move cursor over the flower
(change 'line weight' from thin to medium (using right arrow on the keypad))
Flower is thicker
(change line color to red (using keypad arrows)
Make the flower's stem

Place cursor over middle of flower (press keypad to establish one endpoint)
Move cursor down and to the left (press keypad to establish other endpoint)
Line segment appears
Return to menu
Move cursor over segment
