    Hey guys,

    I was wondering if anyone could help me with the question I have attached. I have several questions to complete just like the one in the attachment as part of revision , so I would really appreciate if someone could show me a step by step of how to complete the question so I can learn from it and complete the rest.

    Thanks in advance to anyone who helps

    This is a standard result.
     \cos \frac{\pi}{6} = \frac{\sqrt 3}{2} .
    Then by symmetry of the cosine curve there is another solution in the range specified. Draw the graph and use symmetry to find the other solution.
