Nov 28 - Differential Equations

We started a short unit on solving differential equations today.

I worked two examples in class. The first represented the situation where

"the rate of growth of y is proportional to y"

This is the definition of exponential growth. It translates to

dy / dx = k*y which can be solved to yield y = Ce^(kx)

The second example exemplified the idea of a limiting value. We'll get more practice with these concepts.

Notes for today are posted below.
