Integration Modeling Settings

Net present value of dividend streams.

Discount future dividends at a rate that decreases to zero to account for the subjective belief that the company will be obsolete in 10 years.

Models of car distance

How much difference does the precise model of velocity versus time make?

Fun on the slide.

Integrate up the instantaneous fun.

Monte Carlo integration

How close is the Monte Carlo method to the actual integral? How would you know how close you are?

Popcorn versus time.

From a sound recording of popcorn (to be made), sketch qualitatively and subjectively the rate of popping against time. Integrate this to get the total subjective amount, then normalize to the actual amount, then differentiate to get the actual rate of popping.
