Question 1 of 8

No calculator

A transformed sine or cosine rule is given by

\[f(x)=\cos\left(\frac{3}{2}x\right)\]

Angles are measured in radians. The domain is \(\left[\frac{4}{3}\pi,\frac{8}{3}\pi\right]\)

(a)4 marks

Fill in the values of a, n, h/π and k. Read the values directly from the displayed rule, writing its argument as n(x−h) with n>0

(b)1 mark

The parameter named in this item is \(n\). Which statement matches that parameter?
