(\partial)/(\partial y)(2x^3y+cos(x^2))

\frac{\partial}{\partial y} (2 x^{3} y + cos (x^{2}))

2 x^{3}

Solution steps

\frac{\partial}{\partial y} (2 x^{3} y + cos (x^{2}))

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (2 x^{3} y) + \frac{\partial}{\partial y} (cos (x^{2}))

\frac{\partial}{\partial y} (2 x^{3} y) = 2 x^{3}

\frac{\partial}{\partial y} (cos (x^{2})) = 0

= 2 x^{3} + 0

Simplify

= 2 x^{3}

\frac{d}{d x} (C e^{3 x})

f (x) = x e^{x^{2}}

\frac{d}{d x} (5 sin (9 x))

\int_{b}^{1} 6 ln (x) d x

\frac{d}{d x} (sin (2 x) + cos^{2} (x))
