Hello, Shaul Salomon. Besides the existing checking for 'forbidden' commands in your Test Suite, which can report false positives (e.g. discussion of "cosine" in comments), you could consider a more complicated regexp statement, or perhaps use the assessFunctionAbsence function described at https://au.mathworks.com/help/coursework/ug/assessfunctionabsence.html . —DIV

@Shaul, people can use 1/sec(x) (which, btw, is also the leading solution) as a solution and you might want to change the test suites accordingly.

The hard way to go about it, but it worked like a charm!
