In many cases, it's acceptable to place an adverb such as now before or after the verb it modifies. (See this page for a good summary of the issue.) For this specific construction, can now is used much more often than now can, the latter of which is unusual enough that it can inhibit understanding in some cases. In fact, when I read your first sentence I initially interpreted it as saying that there is a process called "now" and that this process can (at some indefinite time) be calculated like it is in the book. So go with can now.
