The three things I thought worth noting from this:

(1) The paragraph marker ΒΆ is called a pilcrow or alinea.

(2) The names sin and cos were invented by William Oughtred, whose 1631 book Clavis Mathematicae, The Key to Mathematics was the first use in print of the saltire (, a rotated +) for multiplication.

(3) Traditionally serif faces included a six-pointed asterisk, while sans serif asterisks had five, but in practice this is no longer an observed convention.
