Suppose a function, f(t), models the price of a stock at time t. What material in this course could be used to make money by buying and selling the stock?

For a function, f(t), if we are investing in stock we would be interested in when f '(t) is positive, f(t) is increasing. When f '(t) is negative, y(t) is decreasing.An increasing means f' > 0 An increasing growth rate means f" > 0 When f'(t) = 0and f "(t) > 0, there is a local minimum at t. When f '(t) = 0 and f"(t) < 0, there is a local maximum at t. To the left of a minimum, the curve is falling. After the minimum, the curve rises. The slope has changed from negative to positive. The graph bends upward and f "(t)> 0.

The above information will give us a lot of information on when the:Stock prices have peaked. This means it a good time to sell.Stock prices are at bottom. This means it a good time to buy.With this information, we will know when to buy and sell our stock. And maximize the return on our investment.

Therefore the material in this course that could be used to make money by buying and selling the stock will be the Second Derivatives: Bending and Acceleration and particularly the Maximum and Minimum.
