 ##### Page tree The first step in the example is the random determination of the catheti ({k1}, {k2}) of the triangle for the definition of the task.The correct solution, which is the value for the hypotenuse ({hyp}), will be calculated using a MAXIMA equation. In addition, further possible answer options ({a}, {b}, {c}) will also be computed by MAXIMA.For all variables of the type floating point, the display accuracy was set to 2 decimal places.  In the example, the variables will be included in a choice interaction. The variables for the task text can be integrated into the task by entering the variable names {k1} and {k2}. The correct solution ({hyp}) and the alternative answers ({a}, {b}, {c}) can be additionally provided in the form of answer options. The values for the catheti ({k1}, {k2}) will be randomly selected for each participant and each test attempt within the given value ranges.In the example, the following random values were displayed for the variables: {k1} = 4, {k2} = 13.Based on these values and the defined calculation rules, the hypotenuse and the alternative answer options will be calculated, and the following values displayed in the example task: {a} = 17.00, {hyp} = 13.60, {b} = 8.50, and {c} = 5.39 cm.In the example, the correctly rounded solution for the hypotenuse is 13.60 cm. The answer options {a}, {b}, and {c} can be logically excluded due to the knowledge that the hypotenuse is larger than the respective catheti and smaller than the sum of the catheti.
