Highpoints, lowpoints, x intercepts and such.

Explanation:

Basically any point you can calculate. Numbers like the sin of pi/3 or pi/4 things like that. Depending on how detailed you want to make your graph you can choose the ignore some points.

In this case it is most convenient when #x=-1# since #sin(1-1)=sin(0)=0#

similarly you can do #x=pi/3-1#, and now you have #sin(pi/3-1+1)=sin(pi/3)=sqrt(3)/2#.

Other good x values are #x=pi/4-1#, #x=pi/6-1#, #x=(2pi)/3-1#, #x=(5pi)/6-1# and such.

A most simple graph would just contain the high points, low points and the x-intercepts. If you wish to do that just plot down the values #x=-1, x=pi/2-1, x=pi-1#
