Question: A drug is injected into the bloodstream of a patient through her right arm. The concentration of the drug (in milligrams per cubic centimeters) in the bloodstream of the left arm t hours after the injection is given by \[C\left( t \right)=\frac{0.14t}{{{t}^{2}}+1}\]

(a) Find \(C'\left( t \right)\)

(b) Find \(C'\left( 0.5 \right)\) and \(C'\left( 3 \right)\) and interpret the results
