derivative of cos(x+xcos(y)-y)

Solution

\frac{d}{d x} (cos (x) + x cos (y) - y)

Solution

- sin (x) + cos (y) - x sin (y) \frac{d y}{d x} - \frac{d y}{d x}

Solution steps

\frac{d}{d x} (cos (x) + x cos (y) - y)

Apply the Sum/Difference Rule:

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

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

\frac{d}{d x} (cos (x)) = - sin (x)

\frac{d}{d x} (x cos (y)) = cos (y) - x sin (y) \frac{d y}{d x}

= - sin (x) + cos (y) - x sin (y) \frac{d y}{d x} - \frac{d y}{d x}
