derivative of

y = 9 cos (x)

- 9 sin (x)

Solution steps

\frac{d}{d x} (9 cos (x))

Take the constant out:

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

= 9 \frac{d}{d x} (cos (x))

Apply the common derivative:

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

= 9 (- sin (x))

Simplify

= - 9 sin (x)

\frac{x}{x + 2}

\frac{e ^{- s π}}{s ^{2} + 2 s + 2}

\int 7 csc (x) d x

\frac{d}{d x} (2 x - 6)

n = 1 \sum \infty \frac{n}{9 + n}
