Hello, kolosuxu,

It is against ee rules to post emails to direct communications. Also we can't send answers directly: all the answers are to be post here, in the same way I'm writing this now.

About the question, it is not a trivial one. You need a parser to read the string and capable of understanding ASCII codes for numbers, math signs (+ - * ^), trigronometric entities (sin, cos), capable also of execute the calculations under rules of precedence (first ^, then * and /, then + and -). This a good sizing program.

Your may want try the code at
