**Page 147: A journey of a thousand miles…**

*WM: Is there a reason in Chapter 12 you don’t generalize to the integral power rule the way you generalized to the derivative power rule? You’re 3/4 of the way there just given the explanations you have already written.*

**Pages 148-149: In Chapter 4, we noted… // As we’ll see in this chapter**

*MB: p. 148 Again, I think that instead of opposites, you want to say that you do something to f[x] (take its derivative) and you get f’[x]. Now what do you have to do to get back to f[x]?*

**Pages 150-151: As we’ll see, finding anti-derivative… // To see how super easy it is…**

*MB: p. 150 Good and bad anti-derivatives—did you make up these terms? They are another distraction; at this level you don’t have to emphasize peculiar functions.*

*MB: p. 151 I suggest just integrating to a particular value of x, say x_0; not a constant (1). Then clearly F[x_0] is another function. To find its derivative, imagine finding F[x_0+h]. Draw the picture. Fancy that! The derivative of F[x] is just f[x]!*

**Pages 152-153: More generally, the easy way… // This result is so important…**

**Pages 154-155: The best way to find a good anti-derivative… // In this case, trial and error…**

*MB: p. 155 Don’t forget the ‘dx’ in integral.*

**Pages 156-157: Unfortunately, there’s no foolproof method… // And every time you learn something new…**

*MB: p. 156 Why this function?*

*MB: p. 157 Misprint in first equation (x^(-2), not x^2).*

WM: Page 157 – I don’t get the Chekhov’s gun reference. [And then later: I see the Chekhov's gun thing reappears in Chapter 14, so you do go back to it.]

**Page 158: One final point…**
