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.
