(\partial)/(\partial y)(2xcos(y))

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

- 2 x sin (y)

Solution steps

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

Treat

x

as a constant

Take the constant out:

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

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

Apply the common derivative:

\frac{\partial}{\partial y} (cos (y)) = - sin (y)

= 2 x (- sin (y))

Simplify

= - 2 x sin (y)

\int_{1}^{4} - x^{2} + 5 x - 4 d x

\int e^{x - 2 x} d x

x \to \infty lim ((x - 1) \cdot e^{\frac{1}{x - 1}})

x \to 1 lim (\frac{2 - 2 x}{x - 1})
