Sketch the graph of #y= sin theta # for #-pi <= theta <=pi#?
To sketch this we must know 4 common points of the graph.
We know that
This means that
From our knowledge, a sine graph has the coordinates:
Converting these to radians we get:
We know that a sine graph oscillates between
This means we need to label the
Plot the points on the graph and sketch with a nice smooth curve.
Notice that the graph repeats this pattern throughout.
