What do triangle brackets mean?
The angled brackets represent an inner product. The best known one is the scalar product or the dot product. If u=(u1,u2,u3) and v=(v1,v2,v3), then the dot product is given by ⟨u,v⟩=u1v1+u2v2+u3v3.
Can you use two parentheses in a row?
1. Use brackets inside parentheses to create a double enclosure in the text. Avoid parentheses within parentheses, or nested parentheses. Correct: (We also administered the Beck Depression Inventory [BDI; Beck, Steer, & Garbin, 1988], but those results are not reported here.)
