  • Errors in Section V.3:
    • In Section V.3, lecture notes, there is an error in the example at the bottom of page 4. When I swapped in AB in the denominator of the second to last line, I dropped the square root over the 8. The answer then is 81.9 degrees instead of 87.1 degrees. Sorry! The .pdf has been updated.
