| Corrected version posted 8pm 2/7/05. (No need to re-download. The correction was in Example 2 near the top of page 3. It said "x+1=x-1+1" and it should have said "x+1=x-1+2". This error propagates through the problem. The "1 over square root of 15" should be "2 over square root of 15" in the final answer. Thanks Jim!) |
