OK,
1LD:, you're new, but I have to tell you to check the
forum rules, specifically we want to see your attempt. This isn't an answer posting service, so a scanned image, with little red marks, isn't effort on your part. There's no reason to host your image questions on your Deviant Art page either. If you want to advertize your art, do it elsewhere. If you can't figure out our attachment procedure, use a free image hosting service that shows just your image.
I've locked this thread, and I encourage you to start another one. Ask a question, actually typing it out. Show us your attempt, using actual formulas you may find in the chapter of your book or your class notes, and we'll try to give you a hit to where you've become stuck.
