Can someone tell me how to find the frequency from the complex number?
Please help.

No. The frequency will depend on how the number changes.
A number being complex doesn't make it special from a frequency point of view - it offers nothing more than a purely real number, except that you can use it to represent a signal with an asymmetric spectrum (e.g. positive frequencies without corresponding negative frequencies).
Maybe you mean A*exp(j*w*t)? In which case the frequency is "w" (and "*" is "times", not conjugate).

Give us something specific. Nobody knows what you mean, that's why there's no answer so far. What specific problem are you trying to solve?
email me if you like, or email h_chalker@yahoo.com.au, because by the time you read this I won't be on Answers any more.

Do you mean the argument?i.e. z when the complex number w=x+iy is put in the form w=r(cos z +i sin z) ?
z = tan^-1 (y/x)
