Problems 10-15
Trace out the figure in the book on your paper and then draw a secant line (using a
straightedge). Now, let the second point on the curve approach (along the curve) the
given point and rotate your straightedge along different secant lines until you reach
what you think is the tangent line. Use your straightedge to draw this line (if possible).
See the tangent problem in the text.
