(\partial)/(\partial y)(ycos(6x))

\frac{\partial}{\partial y} (y cos (6 x))

cos (6 x)

Solution steps

\frac{\partial}{\partial y} (y cos (6 x))

Treat

x

as a constant

Take the constant out:

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

= cos (6 x) \frac{\partial}{\partial y} (y)

Apply the common derivative:

\frac{\partial}{\partial y} (y) = 1

= cos (6 x) \cdot 1

Simplify

= cos (6 x)
