Use the properties of the derivative to find the following.

$r(t)=ti4tj{t}^{2}k,u(t)=4ti{t}^{2}j{t}^{3}k$

$($a$)r^{\text{'}}(t)$

$$

$($b$)\frac{d}{dt}[2r(t)-u(t)]$

$$

$($c$)\frac{d}{dt}[(4t)u(t)]$

$$

$($d$)\frac{d}{dt}[r(t)*u(t)]$

$$

$($e$)\frac{d}{dt}[r(t)u(t)]$

$$

$($f$)\frac{d}{dt}r(4t)$

$$
