Q2(g): There is no need to sketch using GC :)
- For 0 < x <= pi, sketch the graph of cos x.
- For pi < x <= 2pi, sketch the graph of x - pi that is a straight line passing through (pi, 0) and (2pi, pi).
- For other regions of x, sketch the horizontal line that coincides with the x-axis.
Be sure to indicate closed circle or open circle in your sketch.

It depends on which acute angle you're looking at when drawing the associated right angle triangle.
However, since the triangle is a right angle isoc. triangle, it does not matter since both the opposite and adjacent sides will be of equal length.
