derivative of x^3+y^3-3xy

Solution

\frac{d}{d x} (x^{3} + y^{3} - 3 x y)

Solution

3 x^{2} + 3 y^{2} \frac{d y}{d x} - 3 (y + x \frac{d y}{d x})

Solution steps

\frac{d}{d x} (x^{3} + y^{3} - 3 x y)

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (x^{3}) + \frac{d}{d x} (y^{3}) - \frac{d}{d x} (3 x y)

\frac{d}{d x} (x^{3}) = 3 x^{2}

\frac{d}{d x} (y^{3}) = 3 y^{2} \frac{d y}{d x}

\frac{d}{d x} (3 x y) = 3 (y + x \frac{d y}{d x})

= 3 x^{2} + 3 y^{2} \frac{d y}{d x} - 3 (y + x \frac{d y}{d x})
