You would need to be more specific.
R & H uses a pretty elementary level of mathematics, Electrical Engineering needs a much higher level than this (this is not a criticism of R&H).
Electrical Engineering also draws on many supporting subjects besides mathematics.
Normally you would have a supporting book XXXX for electrical engineers. R&H tries to tell you what you need to know about supporting subjects ie it tries to be comprehesive.
I do not know of an Electrical Engineering book that attempts to be as comprehensive.
Electrical Technology by Hughes
is a good basic book at about the same level as R&H, but wiht the comprehensive proviso.
