Question

for my CSE 1010 course I solved every single problem in my text book. Sense it's a electronic file I could easily publish it to the internet. My only concern is copyrights behind all of it. All work in the file is all my work, except for a few exceptions when I had to ask for help. I can chose to publish this file to the internet if I wish right with out breaking any laws? The actual wording of the problems is not included in the file just the solutions. I don't see why I wouldn't be able to do this, but I just wanted to make sure before I did.
