(\partial)/(\partial x)(y^5cos(4x))

\frac{\partial}{\partial x} (y^{5} cos (4 x))

- 4 y^{5} sin (4 x)

Solution steps

\frac{\partial}{\partial x} (y^{5} cos (4 x))

Treat

y

as a constant

Take the constant out:

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

= y^{5} \frac{\partial}{\partial x} (cos (4 x))

Apply the chain rule:

- sin (4 x) \frac{\partial}{\partial x} (4 x)

= - sin (4 x) \frac{\partial}{\partial x} (4 x)

\frac{\partial}{\partial x} (4 x) = 4

= y^{5} (- sin (4 x) \cdot 4)

Simplify

= - 4 y^{5} sin (4 x)

\frac{\partial}{\partial x} ((x^{2} + y^{2})^{- \frac{15}{2}} x)

x \to 0 - lim (\frac{3}{x})

\frac{d}{d x} ((ln (x))^{6})

\int \frac{x ^{3} - 3 x ^{2} + 5}{x - 3} d x

\frac{1}{1 - x}, 24
