    Christian Lawson-Perfect commented on Mystery derivatives 8 years, 9 months ago

    The problem here is caused by GeoGebra, which for reasons known to itself adds about 8000 variables to the top-level scope, one of which is called 'ko'.

    I posted a bug report on the GeoGebra forum, and Michael Borcherds has made a new version of the worksheet which avoids the CAS, which he reckons is the root of the problem.
