Give any introductory information the student needs.

No variables have been defined in this question.

#### Warning

• When applying the function,
##### Suggestions
• Change the signature of parameter from to .

This variable is an HTML node. HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

Describe what this variable represents, and list any assumptions made about its value.

← Depends on:
→ Used by:

This variable doesn't seem to be used anywhere.

#### Error in variable testing condition

There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.

No parts have been defined in this question.

Select a part to edit.

The correct answer is an equation. Use the accuracy tab to generate variable values satisfying this equation so it can be marked accurately.

#### Checking accuracy

Define the range of points over which the student's answer will be compared with the correct answer, and the method used to compare them.

#### Variable value generators

Give expressions which produce values for each of the variables in the expected answer. Leave blank to pick a random value from the range defined above, following the inferred type of the variable.

#### String restrictions

For each choice, specify the number of marks to add or subtract when the student picks it.

For each choice, write 1 if the student should tick it, or 0 if they should leave it unticked.

You must set a maximum number of marks in order to use this marking method.

You must set a maximum number of marks in order to use this marking method.

For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.

For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.

Both choices and answers must be defined for this part.

#### Test that the marking algorithm works

Check that the marking algorithm works with different sets of variables and student answers using the interface below.

Create unit tests to save expected results and to document how the algorithm should work.

There's an error which means the marking algorithm can't run:

#### Question variables

These variables are available within the marking algorithm.

Name Value

#### Marking parameters

These values are available as extra variables in the marking algorithm.

Name Value

#### Part settings

These values are available as entries in the settings variable.

#### Unit tests

No unit tests have been defined. Enter an answer above, select one or more notes, and click the "Create a unit test" button.

The following tests check that the question is behaving as desired.

### This test has not been run yet This test produces the expected output This test does not produce the expected output

This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.

One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.

Run this script the built-in script.

This script runs after the built-in script.

To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.

In order to create a variable replacement, you must define at least one variable and one other part.

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:

These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.

This part can't be reached by the student.

Add a "next part" reference to this part from another part.

None of the parts which can lead to this part are reachable either.

### Next part options

Define the list of parts that the student can visit after this one.
