- All problems are directly from the text.
- You may use note cards.
- The note cards may contain
- The formulas for converting between polar and rectangular coordinates
- The symmetry tests for polar coordinates
- The equations for lines, circles, cardiods, limacons, lemniscates, spirals, roses, and conic
sections with an accompanying graph. The equations must be the generic ones with a's
