I'm new here and I would like to know what teachers have saw in their experience about errors in students exams;
I'm interested to know what are the most common errors in exams about "calculus", more specific about:
- studying a function with $\ln$, $e$, $x^2/x$, $\cos$, $\sin$... (domain, zeros, $f'(x)$, $f''(x)$, asymptote)
- calculating an integral (indefinite and definite) by parts and substitution
- calculating the derivative of complex/compound functions
- theorems like Lagrange, Rolle and Bolzano...
I'm asking this because I'm preparing for an exam and I would like to know what are the most common errors, from the "smallest" one to the "biggest" one..
thanks for your help
