hehehe......... last time i had to do it was...... uhhmmm, july 2000

trouble is, im prolly gonna have to do alot of that stuf next year again at the university

hmmmm, just found out there is no solution........

since r/s will be a numer smaller than 0
ln (r/s) will be a negative numer

and you cant take the log (with a positive base) of a negative numer

so no real nummer is in the solution..........
