Webbsin ( α + β) = = sin α cos β + cos α sin β sin ( α − β) = = sin α cos β − cos α sin β sin α + sin β = = 2 ⋅ sin α + β 2 ⋅ cos α − β 2 sin α − sin β = = 2 ⋅ cos α + β 2 ⋅ sin α − β 2 sin 2 α = 2 ⋅ sin α cos α sin ( − α) = − sin α sin α 2 = 1 − cos α 2 Webb24 apr. 2012 · Rešenje: Da bi našli tačnu vrednost sin (α + β), koristićemo formulu za sinus zbira: sin (α + β) = sin α cos β + cos α sin β. Vrednosti sin α i sin β su nam poznate, međutim vrednosti cos α i cos β moramo pronaći. Koristićemo sin2 α + cos2 α = 1, da bi našli nedostajuće kosinusne vrednosti. Za α imamo: WebbHalf Angle Formula - Sine We start with the formula for the cosine of a double angle that we met in the last section. cos 2 θ = 1− 2sin 2 θ Formula Summary We derive the following formulas on this page: \displaystyle \sin { {\left (\frac {\alpha} { {2}}\right)}}=\pm\sqrt { {\frac { { {1}- \cos {\alpha}}} { {2}}}} sin(2α) = ± 21 −cosα easy fast loans no credit check
