For the graph y = cos x
a) What is the maximum value of y ?:: 1
 For what values of x does this occur?:: x = 0
------------------------------------------------
b) What is the minimum value of y ? :: 0
For what values of x does this occur?:: pi/2; (3/2)pi
----------------------------------------------------
c) What is the range of the function?:: [-1,1]
---------------------------------------------
d) What is the y-intercepts?:: (0,1)
---------------------------------------------
e) What is the x-intercepts?:: (pi/2,0); ((3/2)pi,0)
---------------------------------------------------------
f) In which interval(s) is sin x decreasing ?:: [pi/2,(3/2)pi]
g) In which interval(s) is sin x increasing ?:: [0,pi/2]U[(3/2)pi,2pi]
