Relazione fondamentale: sin2 x+ cos2 x= 1 jsinxj= p 1 cos2 x, jcosxj= p 1 sin2 x jsinxj= tanx p 1 + tan2 x, jcosxj= 1 p 1 + tan2 x. Formule di addizione Formule di prostaferesi sin(x+ y) = sinxcosy+ cosxsiny sinx+ siny= 2sin x+ y 2 cos x y 2 sin(x y) = sinxcosy cosxsiny sinx siny= 2sin x y 2 cos x+ y 2 cos(x+ y) = cosxcosy sinxsiny cosx+ cosy

=⇒ cos(x− y) = cosxcosy + sinxsiny which is the fourth addition formula. Replacing y by −y gives cos(x+ y) = cosxcos(−y)+ sinxsin(−y) = cosxcosy − sinxsiny which is the third addition formula. Now, replacing x by π 2 − x gives cos π 2 −x+ y = cos π 2 −x cosy − sin π 2 −x siny Recalling that sin π 2 −z = cosz and cos

This function can be differentiated using the "quotient rule":. {\displaystyle {\begin{aligned}\sin(-x)&=-\sin(x)&\sin \left({\cfrac {\pi }{2}}-x\right)&=\cos(x)&\sin \left(\pi -x\right)&=+\sin(x)\\\cos(-x)&=+\cos(x)&\cos \left({\cfrac {\pi }{  Om man har en graf, till en funktion f(x) = a sinx + b cosx som går genom punkterna (0(grader), 2), och (60(grader), 0).
