På motsvarande sätt har y = cos x. 2 perioden. 360°. 1/2. = 720°. Amplitud och period påverkas inte av att en kurva förskjuts. y = A sin kx har amplituden A och
Exempel 2. Derivera $ f(x)=cos(4x-90) $. Lösning: Här gäller att den inre funktionen är $ u=4x-90$ och den yttre blir då $ cosu $.
The given equation transforms to: 2cos^2 x - cos x - 1 = 0. Solve this quadratic equation for cos x. Since a + b + c = 0, use shortcut. There are 2real roots: cos x = 1 and cos x = c/a = - 1/2. a. cos x = 1 --> x = 0 or x = 2pi b.

Inre funktionen:(2+cos x)=u Inre derivata: u’=-sinx Yttre funktionen: u^3 Yttre derivata: 3u^2=3(2+cosx)^2 Detta ger: y’=3u^2∙u’ = 3(2+cosx)^2∙(-sinx) =3(cosx)^2 ∙(- sinx) När jag skriver in funktionen på tex wolfram alpha så står det att derivatan till funktionen blir:-3(2+cos(x))^2∙sin(x) Vart har jag gjort fel i min uträkning?
