(a) Copy and complete the table of values for y = 3 sinx + 2 cos x for 0 degrees </ x</ 360 degrees
(c) Use your graph to solve the equation: 3sinx +2cosx +1.5.
(d) Find the range of values of x for which 3sin x + 2 cos x < - 1
This question was very unpopular with the candidates. Some of those who attempted this question could not plot the graph correctly. They also displayed significant weakness in reading from the graph.
