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

x cos (x)

Solution steps

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

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (cos (x)) + \frac{d}{d x} (x sin (x))

\frac{d}{d x} (cos (x)) = - sin (x)

\frac{d}{d x} (x sin (x)) = sin (x) + x cos (x)

= - sin (x) + sin (x) + x cos (x)

Simplify

= x cos (x)

x y^{^{'}} - y^{2} = x y^{2}

f (x) = 8 sin^{3} (x)

\frac{d}{d x} (\frac{( 5 x ^{5} - 3 )}{( - 3 x ^{3} + 1 )})

y = 2 (6 x^{2} - 42 x + 49)

f (x) = 25 x
