. It just so happened that one of the other superheroes had been flying in some hydrocodone bitartrate as a cough suppressant for the people who had caught influenza in the previous story. The concentration of hydrocodone bitartrate in the bloodstream, after a 10 mg oral dose, is modeled by nanograms per milliliter (ng/ml) when t is the time after consumption of the drug in hours.   a. How long does it take for the drug to reach peak concentration in the blood? What is the peak concentration?   b. When is the concentration in the bloodstream decreasing the fastest?   c.If the minimum effective concentration is 0.5 ng/ml, when should the next dose be administered

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
