derivative of

a^{7} + cos^{7} (x)

- 7 cos^{6} (x) sin (x)

Solution steps

\frac{d}{d x} (a^{7} + cos^{7} (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (a^{7}) + \frac{d}{d x} (cos^{7} (x))

\frac{d}{d x} (a^{7}) = 0

\frac{d}{d x} (cos^{7} (x)) = - 7 cos^{6} (x) sin (x)

= 0 - 7 cos^{6} (x) sin (x)

Simplify

= - 7 cos^{6} (x) sin (x)

\int_{3}^{4} (x^{3} - π x^{2}) d x

\frac{d}{d x} (\frac{- 7 x}{2 x - 1})

\frac{\partial}{\partial x} (9 x + 16 ∣ y ∣)

\int \frac{1}{( x ( ( 4 x ^{2} - 9 ) ) )} d x

x \to 5 lim (2 x - 7)
