### ** Examinations: **

####
There is a two-hour written examinations in Mathematical Methods in Economics and Business (in February).
As working tools are allowed:

a pocket calculator according to the instructions of FWW and

EITHER TWO individually prepared ONE-SIDED sheets of paper with arbitrary material

OR textbook `Mathematics of Economics and Business' by Werner and Sotskov

Every student should indicate the chosen variant on the cover sheet of the examination paper ('2' stands for 'two pages' and
'B' stands for 'book'). Note that the use of a collection of (handwritten or printed) copies of pages (of whatsoever) is NOT allowed.

A selection of old examinations (in the related subjects Mathematics I and Mathematics II) including answers to the problems can be found under

`Lehrmaterial' of the Faculty of Mathematics
within the part `Klausuren'.
