Example (test) callculation documents written in Cyrillic (Russian Language)

One can open this file with wxMaxima and put Ctl+R command.
Then all calculations will be calculated if every thing will work fine.
On some places wxMaxima may ask if some variable is positive or negative, where
one can 
put just "positive" + Enter and it will continue.
In such formula one can put the statement "assume positive" or "assume
negative" to avoid 
this.
