Impara online a risolvere i problemi di equazioni differenziali passo dopo passo. d/dx(y=cos(x)(7x+2)^(1/2)). Applicare la formula: \frac{d}{dx}\left(a=b\right)=\frac{d}{dx}\left(a\right)=\frac{d}{dx}\left(b\right), dove a=y e b=\sqrt{7x+2}\cos\left(x\right). Applicare la formula: \frac{d}{dx}\left(x\right)=1. 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=\sqrt{7x+2}\cos\left(x\right), a=\cos\left(x\right), b=\sqrt{7x+2} e d/dx?ab=\frac{d}{dx}\left(\sqrt{7x+2}\cos\left(x\right)\right). Applicare la formula: \frac{d}{dx}\left(x^a\right)=ax^{\left(a-1\right)}\frac{d}{dx}\left(x\right), dove a=\frac{1}{2} e x=7x+2.
