    Angle modulation applied math

    Given an angle modulated signal is:

    Xc(t)=10cos[10^8 pi t + 5sin(2 pi 10^3 t)]

    Find the maximum phase deviation and the maximum frequency?

    However, my text's notation says:

    The maximum-frequency deviation in an FM system is given by


    And, the modulation index is defined as

    Note: Where W denotes the bandwidth of the message signal.
    If this was FM and we related it to "bandwidth" that would be easy! BW = infinite.
