These problems are basically definitions that you need to know for this section. It would be a good idea not only to look them up to answer these questions, but also to study.[/tippy]

**[tippy title=”Problems 9-13″]Problems 9-13**

See the box labeled GENERAL FORM. These problems are also dealing with information that you should study for this chapter.[/tippy]

**[tippy title=”Problems 14-15″]Problems 14-15**

Follow the directions; a compass will help. See Example 1.[/tippy]

**[tippy title=”Problems 16-19″]Problems 16-19**

Use parabola graph paper; see Example 2.[/tippy]

**[tippy title=”Problems 20-21″]Problems 20-21**

Use ellipse graph paper; see Example 3.[/tippy]

**[tippy title=”Problems 22-23″]Problems 22-23**

Use hyperbola graph paper; see Example 4.[/tippy]

**[tippy title=”Problems 24-27″]Problems 24-27**

Look at the box labeled “GENERAL FORM” to help you identify these conic section. Also, see Example 5.[/tippy]

These are circles with center located at the origin. Identify the radius by comparing the given equation with the equation *x*2 + *y*2 = *r*2. It will help if you use a compass to draw these circles.[/tippy]

Graph these ellipses by first putting the equations in standard form, as illustrated by Example 6.[/tippy]

**[tippy title=”Problems 35-37″]Problems 35-37**

Graph these ellipses by first putting the equations in standard form, as illustrated by Example 7.[/tippy]

**[tippy title=”Problems 38-43″]Problems 38-43**

Graph these hyperbolas by drawing the central rectangle and the slant asymptotes as shown by

Example 9. *Bonus:* Problem 41 is the same as Example 9.[/tippy]

**[tippy title=”Problems 44-47″]Problems 44-47**

See Example 9; you will need to change to standard form before graphing. Example 7 shows how to do this for ellipses here you do the same thing for hyperbolas.[/tippy]

### Note: Homework Hints are given only for the Level 1 and Level 2 problems.

However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.

On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.

There are many sources for homework help on the internet.
