derivative of

- cos (t)

sin (t)

Solution steps

\frac{d}{d t} (- cos (t))

Take the constant out:

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

= - \frac{d}{d t} (cos (t))

Apply the common derivative:

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

= - (- sin (t))

Simplify

= sin (t)

What is the first derivative of-cos(t) ?
The first derivative of-cos(t) is sin(t)
