Suppose the concentration of a drug in a patient's bloodstream t hours after a treatment is modeled by A(t) = 0.021t 158e units. The concentration after t = 3 hours will be units (round your answer to three decimal places). The concentration will reach 49 units after hours (round your answer to two decimal places).

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.
