(\partial)/(\partial x)(e^ycos(x))

\frac{\partial}{\partial x} (e^{y} cos (x))

- e^{y} sin (x)

Solution steps

\frac{\partial}{\partial x} (e^{y} cos (x))

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= e^{y} \frac{\partial}{\partial x} (cos (x))

Apply the common derivative:

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

= e^{y} (- sin (x))

Simplify

= - e^{y} sin (x)
