Trigonometri A. Jumlah dan Selisih Sudut 1. sin α + β = sin α cos β + cos α sin β 2. sin α - β = sin α cos β - cos α sin β 3. cos α + β = cos α cos β + sin α sin β 4. cos α - β = cos α cos β - sin α sin β 5. tan α + β = tan α + tan β 1 - tan α . tan β 6. tan α + β = tan α - tan β 1 + tan α . tan β B. Identitas 1. sin 2 α + cos 2 α = 1 2. 1 + tan 2 α = sec 2 α 3. 1 + cotan 2 α = cosec 2 α 4. cosec α = 1 sin α 5. sec α = 1 cos α 6. cotan α = 1 tan α 7. tan α = sin α cos α TRIGONOMETRI Reviewed by Rahman on 5:41 PM Rating: 5 No comments Subscribe to: Post Comments (Atom) Materi Pembelajaran ► 2021 (1) ► February (1) ► 2018 (1) ► September (1) ► 2017 (1) ► January (1) ▼ 2016 (19) ► December (5) ► November (10) ▼ October (4) JENIS JENIS MATRIKS TRIGONOMETRI GAMBAR TRIGONOMETRI a + x ...
