sin 2 = q 1 cos 2 cos 2 = q 1+cos 2 tan 2 = q 1+cos tan 2 = 1 cosx sinx tan 2 = sin 1+cos Double-Angle Formulas sin2 = 2sin cos cos2 = cos2 sin2 tan2 = 2tan 1 tan2

= cos2 + 1 + 2sin + sin2 . cos*(1+sin).

You write down problems Then use a trig identity to expand $\sin(2(n-1)x-x)$, simplify and you should see fairly immediately that another trig identity gets you to $2\sin 2nx$ on the -π/2 < y < π/2 và y ≠ 0 y = arccsc( x ) khi và chỉ khi x = csc( y ) Các hàm nghịch đảo có thể được ký hiệu là sin −1 hay cos −1 thay cho arcsin và arccos. (5), Синус двойного угла, sin(2α) = 2sin(α)cos(α). (6), Косинус двойного угла, cos(2α) = cos2(α) – sin2(α) = 2cos2(α) – 1 = 1 – 2sin2(α). (7), Тангенс двойного Формулы приведения. sin(α+2πz)=sinα, cos(α+2πz)=cosαtg(α+2πz)=tgα, ctg(α+ 2πz)=ctgαsin(−α+2πz)=−sinα, cos(−α+2πz)=cosαtg(−α+2πz)=−tgα, The following (particularly the first of the three below) are called "Pythagorean" identities. sin2(t) + cos2(t) = 1.
