خطوات الحلّ

\frac{d}{d x} (3 x + 4)

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

:استعمل قانون الجمع

= \frac{d}{d x} (3 x) + \frac{d}{d x} (4)

\frac{d}{d x} (3 x) = 3

\frac{d}{d x} (4) = 0

= 3 + 0

بسّط

= 3

\frac{d}{d x} (cos^{9} (x^{2} y^{6}))

14 x

x y^{3} + x y = 2, (1, 1)

f (x) = \frac{4}{x ^{2}}, at x = 1

\frac{d}{d x} (\frac{5 x ^{3} + 7 x ^{2}}{x})
