\frac{d}{d y} (x cos (x) y)

x cos (x)

Solution steps

\frac{d}{d y} (x cos (x) y)

Treat

x

as a constant

Take the constant out:

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

= x cos (x) \frac{d y}{d y}

Apply the common derivative:

\frac{d y}{d y} = 1

= x cos (x) \cdot 1

Simplify

= x cos (x)

\int \frac{( sin ^{2} ( x ) )}{x ^{2}} d x

\frac{x ^{2} + 2 x - 8}{x - 1}

\int \frac{a ^{l n (x)}}{x} d x

\frac{1}{1 - 5 x ^{2}}

\frac{d}{d x} (- 2 x)
