Without using MATLAB trigonometric functions, calculate the cosine of an argument x to a precision of 0.0001
Hint: You may wish to consider the cosine Maclaurin series.
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
The hard way to go about it, but it worked like a charm!
