**Calculus word problems** give you both the question and the information needed to solve the question using text rather than numbers and equations. You’ll find a variety of solved word problems on this site, with step by step examples. Some have short videos. Click next to the type of question you want to see a solution for, and you’ll be taken to an article with a step be step solution:

## Calculus Word Problems: General Tips.

Step 1:**Think about what you learned the previous week **in class. Integration? Derivatives? Related rates? Your homework is going almost always be based on what you learned in class the week before, so skim through your notes and/or textbook and look for any relevant formulas.

Step 2: **Read through** the word problem carefully. Don’t skim or skip over phrases and sentences that may seem unimportant. You may miss details that change the entire meaning of the passage. Once you’ve read through the problem once, write down the answer that the question is asking for. Note the format that you need to give the answer in. For example, you might have to give certain units.

Step 3: Break the word problem down into individual statements about the scenario described in the word problem. Record any **numbers** or **equations** given in these statements. Note the units of measurement.

Step 4: Either extract the main equation from the word problem or **build the equation** using the information presented in the statements. Fill in as much of the equation as you can using the information from the word problem.

Step 5: **Solve the equation** to produce any answer needed to satisfy calculus word problems.

Step 6: **Double-check your calculations **and consider whether your answer makes sense in the context of the word problem.

Tips:

- Be sure to state the answer in the format in which it was requested.
- If the equation remains unsolvable, you may need to extract or build more equations using the rest of the available but unused information to answer the empty spaces in your main equation. This is one of the more difficult parts of solving
**calculus word problems**. It’s also one of the most important. Having a solid understanding of calculus, particularly the fact that derivatives represent the rate of change of the equation, will help you when creating the necessary equations.

Does the Calculus Handbook, cover topics from Calculus one, two, and three? Or just one and two?

Does the Calculus Handbook cover advanced Calculus Word Problems?

Just one and two…no advanced word problems, but we’re working on it :)
