The Homework Library (HL) is a database of solved problems.

HL materials are not original and are therefore made available for the sole purpose of studying and learning.
**Misuse of HL materials is strictly forbidden.**

The HL was created for students who need immediate help, and in many cases you can find step-by-step
explanations on how to solve a problem or examples of proper writing, including the use of citations,
references, bibliographies, and formatting.

If you donâ€™t find what you are looking for within our HL database, please reach out to one of our tutors
and schedule a tutoring session.

Assignment #3: Introduction: Mathematics is a dynamic, evolving field of study. Many cultures have contributed to the development of mathematics over time. Research has shown that providing the historical context for a mathematics topic can help students better understand the concept and motiv...

Use the field and subject filters to browse through Homework Library solutions that pertain to your areas of interest. We are adding new content to the library on a daily basis, so check back from time to time. If you'd like us to post solutions in a subject we don't yet have content for, let us know - we'd like to hear from you!

The solutions will include information such as the original question and sometimes a preview of the solution itself. When you are ready to purchase a solution just click on it and it will be yours.

There is no time limit. Once you purchase a solution you'll have access to it for as long as your registration on the site remains valid. If you can log into your account, you can view any purchased solutions.
