(\partial)/(\partial y)(sin(xy^2))

\frac{\partial}{\partial y} (sin (x y^{2}))

cos (x y^{2}) \cdot 2 x y

Solution steps

\frac{\partial}{\partial y} (sin (x y^{2}))

Treat

x

as a constant

Apply the chain rule:

cos (x y^{2}) \frac{\partial}{\partial y} (x y^{2})

= cos (x y^{2}) \frac{\partial}{\partial y} (x y^{2})

\frac{\partial}{\partial y} (x y^{2}) = 2 x y

= cos (x y^{2}) \cdot 2 x y
