Solutions: [HTML] [PDF]

Trigonometry by Gelfand and Saul is often recommended as a precalculus text for self-study. However, those who are learning without the help of a teacher can struggle with the lack of solutions to exercises in the text. It is hoped that this repository will eventually contain a complete set of solutions that can be viewed as HTML or downloaded in PDF format.

Contributions are welcome! Contributions can be:

• new solutions
• alternate solutions
• corrections to existing solutions
• additional information that readers may find useful

If you are comfortable editing the .tex file directly then feel free to submit a pull request. If not, just create a GitHub issue describing your proposed change.

• John Beach published a partial set of solutions (odd numbered exercises only).
• Fardeen Ashraf also published a partial set of solutions (Chapters 1-4).
• Adrian S. Durham published a complete set of solutions for Gelfand's Algebra.
