- Read through example 1 in the text, and watch the applet.
- The white line that you are seeing is the secant line between the two red points. Assume
that you wanted the author of the program to add in the line tangent to the curve at the
left-most red point. How would you describe to the programmer where to draw the tangent line?
(Remember, to specify a line you need to specify a point and a slope)
