Day 5 in MAT229

Today:

• Announcements:
  • $\sin(x)$
  • Apologies for ditching you for the last two sessions. Yours truly was enjoying hanging out with 5000+ of his favorite mathematician friends. Lots of great talks, and I learned a few things; one of my favorite was the importance of
    Productive Struggle

  • How are we doing? Are we struggling productively?
  • How are the homework problems going?
  • I think that I've got IMath set up for multiple attempts (but continual losses, if you keep trying).

• Let's take a look at the materials that Professor Zarnowski went over, and make sure that we're getting comfortable with exponentials, logs, and techniques from calc one on logs and exponentials:

  By the way, since I'm teaching STA205 at the moment, I'm thinking a lot about normal distributions of things (bell-shaped curves). The standard normal probability density is given by \[ \rho(x)=\frac{1}{\sqrt{2 \pi \sigma^2}}e^{-\frac{(x-\mu)^2}{2\sigma^2}} \]

  You statistician wannabes are going to be especially interested in exponentials....
