(\partial)/(\partial x)(xsin(4x^2y))

\frac{\partial}{\partial x} (x sin (4 x^{2} y))

sin (4 x^{2} y) + 8 x^{2} y cos (4 x^{2} y)

Solution steps

\frac{\partial}{\partial x} (x sin (4 x^{2} y))

Treat

y

as a constant

Apply the Product Rule:

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

f = x, g = sin (4 x^{2} y)

= \frac{\partial}{\partial x} (x) sin (4 x^{2} y) + \frac{\partial}{\partial x} (sin (4 x^{2} y)) x

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

\frac{\partial}{\partial x} (sin (4 x^{2} y)) = cos (4 x^{2} y) \cdot 8 y x

= 1 \cdot sin (4 x^{2} y) + cos (4 x^{2} y) \cdot 8 y xx

Simplify

1 \cdot sin (4 x^{2} y) + cos (4 x^{2} y) \cdot 8 y xx : sin (4 x^{2} y) + 8 x^{2} y cos (4 x^{2} y)

= sin (4 x^{2} y) + 8 x^{2} y cos (4 x^{2} y)

y^{^{'}} = \frac{2 x}{( 1 + 2 y )}

\int \frac{x}{x ^{4} - 6 x ^{2} + 5} d x

\frac{d}{d x} (lo g_{3} (x^{2} + 1))

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

\frac{d}{d t} ((t - 2)^{2})
