Lesson 8.0: Greek Letters

Explanation

The Greek alphabet is frequently used in mathematics. Greek letters are formed with the dots four six prefix, followed by the letter. The Greek letter modifier applies to the next letter only. If the letter is capitalized, the prefix is preceded by dot six. The grade 1 indicator is not used with Greek letters. The most commonly used Greek letters are listed here. A complete list of upper and lower case Greek letters can be found in Guidelines for Technical Materials (2014) §11.7.
