derivative of

f (x) = 5 x^{2} cos (x) - 4 x

5 (2 x cos (x) - x^{2} sin (x)) - 4

Solution steps

\frac{d}{d x} (5 x^{2} cos (x) - 4 x)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (5 x^{2} cos (x)) - \frac{d}{d x} (4 x)

\frac{d}{d x} (5 x^{2} cos (x)) = 5 (2 x cos (x) - x^{2} sin (x))

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

= 5 (2 x cos (x) - x^{2} sin (x)) - 4

y = arccos (2 x + 3)

\frac{1}{( s + 1 ) ( s - 1 ) ^{2}}

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

y = 6 8 x^{2} + 7

y = x x
