Då f (x) = sin x blir en primitiv funktion F (x) = - cos x eftersom f (x) = F´(x). f (x) = cos x har den En primitiv funktion till f (x) = cos 2x blir. Man får inte glömma att

What is the formula for cos2x? We use the formula cos (A +B) = cos A cos B – sin A sin B, to obtain the formulæ of cos 2x. The formulas of cos (2x) as following: Cos (2x)= 2 (cosx)^2–1. Cos (2x)=1–2 (sinx)^2.
hur löser man denna ekvation, jag har suttit ett tag med den men vet ej hur man löser den. Det skulle uppskattas med hjälp:) Trigonometri är det område av matematiken i vilket sambanden mellan en triangels olika storheter beskrivs med trigonometriska funktioner. Trigonometriska funktioner är sammanfattande benämning på de matematiska funktionerna sinus, cosinus, tangens, cotangens, secans och cosecans. $\begingroup$ $\cos^2(x) = \cos(x)\times \cos(x)$ and $\cos(x^2) = \cos(x \times x)$ So no. But beware, the notation $\cos^{-1}(x)$ is ambiguous.
