derivative of

2 cos (x)

- 2 sin (x)

Solution steps

\frac{d}{d x} (2 cos (x))

Take the constant out:

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

= 2 \frac{d}{d x} (cos (x))

Apply the common derivative:

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

= 2 (- sin (x))

Simplify

= - 2 sin (x)

(1, 6), (5, 8)

e^{- x}

y = csc (x) cot (x)

y = x^{2}

(4, \frac{4 π}{3})
