Gabhaidh diofarachadh ann an abairtean ailseabrach is/no triantanachd a chleachdadh gus reatan atharrachaidh, puingean suidhichte is an nàdar obrachadh a-mach, no caisead no co-aontar tansaint don lùb

Nuair a bhios tu a' diofarachadh abairtean triantanachd, cuimhnich:
\(y = \sin x \to \frac{{dy}}{{dx}} = \cos x\)
\(y = \cos x \to \frac{{dy}}{{dx}} = - \sin x\)
Diofaraich \(y = 4\cos x\)
\(\frac{{dy}}{{dx}} = - 4\sin x\)
Diofaraich \(y = 3x + 2\sin x\)
\(\frac{{dy}}{{dx}} = 3 + 2\cos x\)
