Impara online a risolvere i problemi di passo dopo passo. d/dx(2cos(xy)=3x+7y). Applicare la formula: \frac{d}{dx}\left(a=b\right)=\frac{d}{dx}\left(a\right)=\frac{d}{dx}\left(b\right), dove a=2\cos\left(xy\right) e b=3x+7y. Applicare la formula: \frac{d}{dx}\left(cx\right)=c\frac{d}{dx}\left(x\right). Applicare l'identità trigonometrica: \frac{d}{dx}\left(\cos\left(\theta \right)\right)=-\frac{d}{dx}\left(\theta \right)\sin\left(\theta \right), dove x=xy. Applicare la formula: \frac{d}{dx}\left(ab\right)=\frac{d}{dx}\left(a\right)b+a\frac{d}{dx}\left(b\right), dove d/dx=\frac{d}{dx}, ab=xy, a=x, b=y e d/dx?ab=\frac{d}{dx}\left(xy\right).
