derivative of

y = 7 cos (x)

- 7 sin (x)

Solution steps

\frac{d}{d x} (7 cos (x))

Take the constant out:

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

= 7 \frac{d}{d x} (cos (x))

Apply the common derivative:

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

= 7 (- sin (x))

Simplify

= - 7 sin (x)

\int t^{2} \cdot ln^{2} (t) d t

x \to 0 lim (x^{- 3})

\frac{d}{d x} (4 x^{- \frac{1}{3}} + \frac{9}{x ^{\frac{5}{3}}})

\frac{d y}{d x}, x cos (2 x + 3 y) = y sin (x)

\int 2 t - t - \frac{9}{t ^{2}} d t
