36. Drug pharmacokinetics A patient is injected with a drug every 12 hours. Immediately before each injection the concentration of the drug has been reduced by 90% and the new dose increases the concentration by 1.5 mg/mL. (a) What is the concentration after three doses? (b) If C, is the concentration after the nth dose, write a dif- ference equation that expresses C₂+1 in terms of Cn. (c) Find a formula for C as a function of n. (d) What is the limiting value of the concentration?
