| 33 | == Random selection == | ||
| 34 | |||
| 35 | Define a value list from which a value is randomly selected. The alternative values are separated by a line break, comma, or semicolon. | ||
| 36 | |||
| 37 | If the selection value contains a comma, a backslash needs to be inserted before the comma. //(Example: "The condition\, which ...")// | ||
| 38 | |||
| 39 | **Possible entries are for example:** | ||
| 40 | |||
| 41 | * //Random selection: Car; motorcycle; bicycle: //One of the specified values will be randomly selected, for example "bicycle". | ||
| 42 | |||
| 43 | |||
| 44 | {{info}} | ||
| 45 | The following examples for the use of numerical variables to generate random values show typical application scenarios: | ||

| 51 | == Direct value assignment == | ||
| 52 | |||
| 53 | You can directly assign a value to all types of variables in order to initialise them. Later on, the value can be changed depending on other variables (cf. conditions). | ||
| 54 | |||
| 55 | **Possible entries are for example:** | ||
| 56 | |||
| 57 | * //Value: Hans: //The variable is assigned the value "Hans". | ||
| 58 | * //Value: The function increases linearly: //The variable is assigned the value "the function increases linearly". | ||
| 59 | |||
| 60 | == Calculation (MAXIMA) == | ||
| 61 | |||
| 62 | [[MAXIMA>>url:http://maxima.sourceforge.net/||shape="rect"]] allows for the work with strings and formulas. You can calculate variable values on the basis of other variables. Indicate your calculation rule in MAXIMA notation. | ||
| 63 | |||
| 64 | {{info}} | ||
| 65 | For further information on the MAXIMA notation, please refer to the [[MAXIMA Manual>>url:http://maxima.sourceforge.net/docs/manual/de/maxima.html||shape="rect"]]. A valuable compilation of examples can be found in the form of a wiki under [[MAXIMA good practice examples>>url:https://bildungsportal.sachsen.de/opal/auth/RepositoryEntry/5499682817/CourseNode/93229879750473/wiki/Index||shape="rect"]]. | ||

| 68 | **Possible entries are for example:** | ||
| 69 | |||
| 70 | * //Calculation (MAXIMA): string({a}*x+5): //A simple function equation is calculated including the variable value {a}. Plase note that the variable {a} must have been previously defined. | ||
| 71 | * //Calculation (MAXIMA): string(integrate({function},x,0,1)): //MAXIMA enables complex mathematical calculations. The derivative of a sample function (e.g. 5*x+5) could result in the value "15/2". | ||
| 72 | * //Calculation (MAXIMA): tex1(matrix([{a1},{a2}],[{b1},{b2}])): //MAXIMA also facilitates the return of latex content. | ||
