Hello sir, I don't mind helping. God knows we all need help sometimes but if your professor asked you to complete this then you must be at a level where you should be able to figure this yourself, if you have been keeping up with your studies. Perhaps you need to step back, go for a walk or something. Things usually come to me when I take a break and go for a walk.

If that doesn't help try asking your professor to give you the answer and see what he says. No disrespect intended.

Good luck

James
