Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
No. But sin2a equals 1 minus cos2a ... and ... cos2a equals 1 minus sin2a
Treat the "plus positive X" as "minus negative X". Example: Positive two plus positive two equals positive four. Positive two minus negative two equals positive four.
