exp(z*cos(x))=BesselI(0,z)+sum(BesselI(v,z)*cos(v*x),v=1..infinit)

where BesselI is the modified Bessel function of the first kind. The last term is the sum over v from 1 to infinit and v is an integer. Is this correct?

Secondly I am trying to get Maple to do the integral using the modified Bessel functions, but I can't get it to work. Can anybody help me? Thank you for your time.

Best regards
