(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(a)Carefully draw graphs of y=cosx, y=x, y=(1/5)x

(b) From the graphs, determine how many solutions the equation cosx=mx has for m=1 and m=1/5

(c) Add a sketch of y=mx onto your picture, where m is chosen so that cosx=mx has exactlytwosolutions. (without computing the value of m)

(d) Use your sketch to estimate the correct value of m

(e) why is it true that the value of -m will also give exactly two solutions to cosx=mx?

(f)Is it possible to find a value of m such that cosx=mx has exactly three solutions? four? n?

Explain by sketching y=cosx and y=mx for relevant values of m

3. The attempt at a solution

A hint was given to us by the prof:

"you should draw all your graphs on just one diagram like: (the attachment)"

Okay, so I don't have a problem drawing the graphs,but for part (b) and rest

Please Help
