PDF | Tanshinone IIA (Tan 2A) is a lipid‑soluble compound extracted from the Chinese herb Danshen (Salvia miltiorrhiza Bunge). Aug 17, 2011 ... The double angle trigonometric identities can be derived from the addition trigonometric identities. Basically, all you need to do change all of the B's to A's. tan 2A = cot (A - 18°) ⇒ tan 2A = tan [90° - (A - 18°)] ⇒ 2A = 90° - A + 18° ⇒ 2A + A = 108° ⇒
