## 6.19 Mathematical and Logical Operators in Algorithms and Answers

This is a list of mathematical and logical operators (functions) that you can use in internal directives within questions. Some of these operators are also available to students in their responses to math questions in the system (unreserved operations), while others are reserved for instructor or question-authoring use only.

### Unreserved Operations

These functions are available for use in both internal directives (in variable definitions and statements) and for use by students when expressing their responses to math questions. Each command performs the expected mathematical function in a formula or algorithm.

Table 6.15: Mathematical Functions that Students Can Use

 sin, cos, tan arcsin, arccos, arctan csc, sec, cot hypsin, hypcos, hyptan abs, sqrt archypsin, archypcos, archyptan log, ln, exp

### Reserved Operations

The following functions are only available as internal system directives (in variable definitions and statements). These functions are not available to students.
