e^x (I wish I had an easy way to write exponents on this blog.)

Today, we quickly covered the fact that the derivative of e^x is e^x, making it the only nontrivial function whose derivative is itself.  P. 140 #1-14 all were assigned for homework.  We also had a quiz, and hopefully, everyone had sufficient time to finish for once.

Whatever you do, don’t click on this link.  It will take you to a really bad joke related to the derivative of e^x.  I’m serious.  Don’t read it.  It’s absolutely awful.

  1. Unfortunately….. I am sick today but I did the extra credit over and this is what I got for the answer to the second problem….


  2. Very close. Check for a sign error in your derivative. It may occur before or after you substitute in the values for x and y.

  3. The second answer you gave me was correct. I’m sorry I told you differently. (These eyes aren’t what they used to be. I misread the solution.) I’m not going to post your comment because you were the first person to turn in the correct answer, and I’ve only had one other student turn in a correct answer. (I don’t want to give away the correct answer.)
