$y = 7 \cos (t)$

Step 1

Since $7$ is constant with respect to $t$ , the derivative of $7 \cos (t)$ with respect to $t$ is $7 \frac{d}{d t} [\cos (t)]$ .

$7 \frac{d}{d t} [\cos (t)]$

Step 2

The derivative of $\cos (t)$ with respect to $t$ is $- \sin (t)$ .

$7 (- \sin (t))$

Step 3

Multiply $- 1$ by $7$ .

$- 7 \sin (t)$
