    Help with function and its period

    Hey, this function has made me lose my sleep
    I'd really appreciate if someone could help me out solving it
    Here it is:

    How can I procceed with this?

    y= 4cos(x/2) - 3 sin(2x)

    I also want to know its period
    Is there any other way to find it out, but graphing it?
