    Completely random one from my CGP book (edexcel, worth 11 marks):

    Write 5cos\theta +12sin\theta in the form Rcos(\theta -\alpha ), where R>0 and 0\leq \alpha \leq 90.
    Hence solve 5cos\theta +12sin\theta =2 for 0\leq \theta \leq 360^{\circ}, giving your answers to 2 decimal places.
    Use your results from the first part of the question to find the maximum value of (5cos\theta +12sin\theta )^3.

    I have the answers to this as well if you need it.
