Assuming that we are working with the drug model as we've developed in class, let the residual amount of a drug left in a patient's body at the end of the nth dosage period be given by: (observe that each dose is 4mg) - 1 (e0.5)n 4e-0.5 1-e-0.5 If the drug dosing scheme could continue forever, then the limiting eventual maximum drug level and the limiting eventual maximum residual drug level are respectfully given by: 4e0.5 -0.5 ; 4 0.5 - 1 4e0.5 4 e0.5 1 1 - 0.5 4e0.5 e0.5+1 4 e0.5+1 4e0.5 4 e0.5 1 0.5 1 4e0.5 4 e0.5+1 e0.5 ; 1 4e0.5 4 1 e0.5 0.5 1 4e0.5 4 e0.5 1 0.5+1 4e0.5 4 e0.5 -1 ; e-0.51 4e0.5 4 1- 0.5 1 e0.5 4e-0.5 4 e0.5 1 e0.5 1
