cos π/3 = cos 2 π/6– sin 2 2π/6 = ¾ - ¼ = ½ použili sme vzorec pre výpočet dvojnásobného argumentu funkcie kosínus (2) upravili číselné hodnoty

Sum formulas for sine and cosine sin (s + t) = sin s cos t + cos s sin t. cos (s + t) = cos s cos t – sin s sin t. Double angle formulas for sine and cosine sin 2t = 2 sin t cos t The first shows how we can express sin θ in terms of cos θ; the second shows how we can express cos θ in terms of sin θ. Note: sin 2 θ-- "sine squared theta" -- means (sin θ) 2.

použili sme vzťahy pre dvojnásobné argumenty funkcií sínus a kosínus , stačilo by iba pre kosínus. použili sme vzťah pre súčtový vzorec cos2x + sin2x = 1.

Z čitatele a jmenovatele můžeme zkrátit |a| a dostaneme konečný vzorec :. tg3x=3tgx−tg3x1−3tg2x,ctg3x=ctg3x−3ctgx3ctg2x−1. Din formulele pentru cos 2x obtinem: cos2x=1+cos2x2,sin2x=1−cos2x2. Inlocuind pe x cu x2 gasim:. Nechť tedy. (xa) = (e(a·ln x)) = (e(a·ln x)) · (a · lnx) = xa · a ·.

tan –t = –tan t. Sum formulas for sine and cosine sin (s + t) = sin s cos t + cos s sin t. cos (s + t) = cos s cos t – sin s sin t. Double angle formulas for sine and cosine sin 2t = 2 sin t cos t The first shows how we can express sin θ in terms of cos θ; the second shows how we can express cos θ in terms of sin θ. Note: sin 2 θ-- "sine squared theta" -- means (sin θ) 2. Problem 3. A 3-4-5 triangle is right-angled.
