Tidal components Refer to Exercise 49. The principal solar diurnal component may be approximated by

Sketch the graph of f if a = 0.2 m.

Tidal components The height of the tide at a particular point on shore can be predicted by using seven trigono-metric functions (called tidal components) of the form

The principal lunar component may be approximated by

where t is in hours and t = 0 corresponds to midnight. Sketch the graph of f if a = 0.5 m.
