(a) Graph the function f ( x ) = sin x − 1 1000 sin ( 1000 x ) in the viewing rectangle [ – 2 π , 2 π ] by [– 4, 4 ]. What slope does the graph appear to have at the origin? (b) Zoom in to the viewing window [–0.4, 0.4] by [– 0.25, 0.25] and estimate the value of f' (0). Does this agree with your answer from pan (a)? (c) Now zoom in to the viewing window [– 0.008, 0.008] by [– 0.005, 0.005]. Do you wish to revise your estimate for f' (0)?
