Consider the two functions

y = cos 2x + sin x

and

y = 0.01 tanx

where

0 < = x < = 9

We want to estimate the points where the graphs of these two functions intersect. To that end, prepare an xy-table of values, where x = 0.0,0.1, 0 .2 ,..., 9.0 and y = cos 2x + sin x.

a) Graph the curve you have just defined.

b) Superimpose the curve defined by y=0.01 tan x, coloring this latter curve red.

c) Note that there appear to be six places where these two curves intersect. Argue that, in reality, there can be only four points where the graphs of the two functions intersect. Can you give a reason for the two “extraneous” intersection points?

d) Estimate the (x , y) coordinates of the actual intersection points.
