Chapter 13, Problem 76RE

(a)

To determine

To calculate: The total amount of drug released from 1 to 10 hours since the drug is administered, if the rate of release of the drug is given by the function $R\left(t\right)$ in the equation below:

$R\left(t\right)=\frac{4}{3t}+\frac{2}{t^2}$

Here $t$ is the time in hours since the drug is administered.

(b)

To determine

To calculate: The total amount of drug released from 10 to 20 hours since the drug is administered, if the rate of release of the drug is given by the function $R\left(t\right)$ in the equation below:

$R\left(t\right)=\frac{4}{3t}+\frac{2}{t^2}$

Here $t$ is the time in hours since the drug is administered.
