You are most welcome Sheenkay Jaan! I like doing other people's homework so keeping thread-ing your homeworks,lol...I mean keep posting your questions if any...I would always love to help you....Oh by the way, next time you must specify the level of the course or something like if it is a high school or college level course because that way the responders to your questions would be able to narrow down the information to the level of the course.
Good luck!
