For what values of t is msec< man? (Use the interactive figure to find your answer.) The values of t for which msec&...
SOLUTION We will be able to find an equation of the tangent line t soon as we know its slope m. The difficulty is that we know only one point, P, on t, whereas we need two points to compute the slope. Bu observe that we can compute an approximation to m by choosing a nearby point Q(x, 4x?) on the graph (as in the figure) and computin slope mpo of the secant line PQ. [A secant line, from the...
