Synthesized answer
According to the passages, the fundamental difference is that "A as an initial" is used as an abbreviation for words or phrases, while "A as a symbol" stands for a specific concept or notation in a particular field. The text explicitly separates these two categories under distinct headings [2].
A specific example of "A" used as an initial (abbreviation) is "A. B." in nautical language, which stands for "able-bodied seaman" [2]. Another example is "A. M." in horology, meaning "ante meridiem" (before noon) [2]. A specific example of "A" used as a symbol is in logic, where it stands for "a universal affirmative" [2]. Another example is in music, where it represents "the 6th note of the diatonic scale of C major" [2].
The passages clearly define and illustrate both categories with multiple examples, so no information is missing to answer the question.

atonic scale of C major corresponding to the la of the Italians and the French. In heraldry, the chief in an escutcheon. In nautical language, A-1=a vessel of the first class, excellently built. Figuratively, anything highly excellent; the best of its class. In mathematics, A and the other letters of the alphabet are used, e. g. , in Euclid, to represent lines, angles, points, etc. In algebra, a and the other first letters of the alphabet are used to express known quantities, and the last letter to express such as are unknown.
Delta . The old Hebrew, the Aramæan, and the Greek letters seem to have come from the Phœnician, a Syro-Arabian tongue. The Phœnician letters, again, as Gesenius suggests, may have been derived from the Egyptian hieroglyphics. A as an initial is used: In chronology, for Anno (Lat.)=in the year, as A. D., Anno Domini =in the year of our Lord; A. U. C., Anno urbis conditæ =in the year of the city founded— i. e. , from the foundation of the city (Rome)=753 B. C. ( Varro ).
