Secant Lines

Let f(x) = cos(x). Let p=(pi,-1) be a point on the graph y = f(x).

a) calculate the slope of the secant line passing through P and F(pi+0.2), (pi+0.2))

b) calculate the slope of the secant passing through P and (pi-0.1),f(Pi-0.1))

what would your guess on the value of slopes of secant lines passing through P and other points on the graph y=f(x)

Solution Summary
