hello experts,

I was using maple for a physical  problem,

and things turned very complicated with a equation with bessel function in it,

like this BesselI(1, (0.9067480359e-2+0.9067480359e-2*I)*sqrt(f))andBesselI(0., (0.9067480359e-2+0.9067480359e-2*I)*sqrt(f)),

which include complex,

the whole equation is as followed:

the variable is f and RV,,dependent variable is RV.

how am I supposed to plot RV when f=100..4000?

it is certain RV has real part and imaginary part,maybe i need a 3Dplot?

please let me know if you have any idea.

best regards,

want to plot the relationship between RV and f,but how?

 

complexplot(RV, f = 100 .. 4000, labels = ["Re", "Im"])

complexplot(RV, f = 100 .. 4000, labels = ["Re", "Im"])
