I wasn't sure how to approach this problem, but I gave it a shot and now I'm stuck. Can someone please review what I have done.
Thanks
Thank you very much for your help. I seem to have a problem with starting some identities and once I get started, I usually get stuck around the third step in the problem. Do you have any suggestions on the best approach in verifying identities? I know that I should begin with the most difficult side first, but I usually hit a road block once I begin the problem. Any tips, resources, or advice would be very helpful.
Thanks again.
