- In the diagram, the graphs of the functions ƒ(x) = asinx and g(x) = tanbx are drawn on the same system of axes for the interval 0° ≤ x ≤ 225°
- In the diagram below, the graphs of f(x) = cosx + q and g(x) = sin(x + p) are drawn on the same system of axes for -240° ≤ x ≤ 240°. The graphs intercect at (0 °; ½), (-120°, -1) and (240°; -1).
- In the diagram the graph of f(x) = 2sin2x is drawn for the interval x ∈ [-180°; 180°].
