since the drug was administered is given by

C (t) = 15te^(-0.2)t

The area under the concentration curve is a measure of the overall effect of the drug

on the body, called the bioavailability. Find the bioavailability of the drug between

t = 0 and t = 3.

please write the answer with steps

Answer 1

Taha:

Take the integral of C(t) from t =0 to t=3.
