(\partial)/(\partial y)(sin(y)-ysin(x))

\frac{\partial}{\partial y} (sin (y) - y sin (x))

cos (y) - sin (x)

Solution steps

\frac{\partial}{\partial y} (sin (y) - y sin (x))

Treat

x

as a constant

Apply the Sum/Difference Rule:

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

= \frac{\partial}{\partial y} (sin (y)) - \frac{\partial}{\partial y} (y sin (x))

\frac{\partial}{\partial y} (sin (y)) = cos (y)

\frac{\partial}{\partial y} (y sin (x)) = sin (x)

= cos (y) - sin (x)
