Functions, Control, and Getting Help
- Getting Help. Sage has extensive built-in documentation, accessible by typing the name of a function or a constant (for example), followed by a question mark.
- Creating Subroutines and Functions in Sage Making custom subroutines in Sage.
- Built-In Functions. Sage has many built-in functions such as sin(x).
- Piecewise Defined Functions. Piecewise functions in a single variable can be defined in Sage.
- Counting and Iteration. In Sage, you count by iterating over a range of integers.
- Iteration, Tables, and String Formatting. One easy way to print a table with a for loop is to use string formatting.
- Linking Several Sage Cells. It is possible to link two or more Sage cells so that a cell will remember any computations does in previous cells.
- Formatting Sage Output with show. You can use the show command or method to present Sage output in a nice mathematical format.
