About Trig Graphs 

A Trig Graph exam question is shown below:

“Part of the graph of y = asinbx° is shown in the diagram. State the values of a and b”


Source: N5 Maths, 2015, P1, Q6

Trig graphs are graphs of trigonometrical functions such as y = sin x°, y = cos x° or y = tan x°.

You need to know how trig graphs change for functions such as:

  • y = 3 sin x°           (amplitude is 3, period is 360°)
  • y = cos 2x°           (amplitude is 1, period is 180°)
  • y = cos 2x° + 1     (above graph shifted up 1)
  • y = cos(x – 90)°   (cos wave shifted to the right 90°)
