Integral of sinasinb
NettetSin(A+B) = SinASinB + CosACosB Cos(A+B) = CosASinB - SinACosB Cos(A-B) = CosA.SinB + SinA.CosB itu 4 identitas yg cukup penting, kalo pembahasannya agak panjang, ntar guru kamu juga jelasin kok. tapi menurut gue, penjelasannya nggak cukup berarti, identitas trigonometri emang harus dihafal Semangat belajar yaa =) Nettet24. nov. 2016 · Use trigonometry to rewrite. When studying trigonometry, some encounter formulas called "Power Reduction Formulas". These are not used for anything -- until one studies integration. Many (most?) students who encounter these formulas forget them before they need them. cos(A+B) = cosAcosB-sinAsinB, so cos(2A) = cos^2A - sin^2A …
