Created this as a copy of Differential equation with a repeated linear factor & a delta function: X(s).No variables have been defined in this question.
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.

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:

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 Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.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.
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.
Variable  Answer to use  Must be answered?  

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.
