I. 128. Prepare a LaTeX document describing the main properties of the sine and cosine functions. It should contain at least three identities, and the graphs of the functions. You should also tabulate the values of the functions at 0,1,...,90 degrees to 4 digits.
The beginning of the text should contain the usual KöMaL-header (number of the problem, name, city, class, school, e-mail address). The automatic numbering feature of LaTeX for tables, formulae and figures should be used, and you should refer to these using labels.
Both the LaTeX source code (i128.tex) and its converted PDF version (i128.pdf) should be submitted.
Deadline expired on 18 April 2006.
