(\partial)/(\partial x)(-6xysin(xy^2))

\frac{\partial}{\partial x} (- 6 x y sin (x y^{2}))

- 6 y (sin (x y^{2}) + x y^{2} cos (x y^{2}))

Solution steps

\frac{\partial}{\partial x} (- 6 x y sin (x y^{2}))

Treat

y

as a constant

Take the constant out:

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

= - 6 y \frac{\partial}{\partial x} (x sin (x y^{2}))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = sin (x y^{2})

= - 6 y (\frac{\partial}{\partial x} (x) sin (x y^{2}) + \frac{\partial}{\partial x} (sin (x y^{2})) x)

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

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

= - 6 y (1 \cdot sin (x y^{2}) + cos (x y^{2}) y^{2} x)

Simplify

= - 6 y (sin (x y^{2}) + x y^{2} cos (x y^{2}))

3 x, \frac{1}{x}, 8, 1

\int x^{3} a x^{4} - b d x

\frac{1}{( x ^{2} - 1 ) ( x ^{2} + x + 1 )}

e^{- x^{2}} 1

\int sin (x) + x d x
