What are the important points to graph #y=sin(x+1)#?
Highpoints, lowpoints, x intercepts and such.
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
similarly you can do
Other good x values are
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
