Answer :
[tex]y=- \frac{1}{3} x^{6} [/tex]
[tex] \frac{dy}{dx} =- \frac{d x^{6} }{dx 3} [/tex]
[tex] \frac{dy}{dx}= -\frac{1}{3} 6 x^{5} [/tex]
[tex] \frac{dy}{dx}=-2 x^{5} [/tex]
[tex] \frac{dy}{dx} =- \frac{d x^{6} }{dx 3} [/tex]
[tex] \frac{dy}{dx}= -\frac{1}{3} 6 x^{5} [/tex]
[tex] \frac{dy}{dx}=-2 x^{5} [/tex]
