A hospital patient receives intravenously 5 units of a certain drug per hour. The drug is eliminated exponentially, so that the fraction that remains in the patient's body for t house is f(x)=exp(-0.1t) . If the treatment is continued indefinitely, approximately how many units of the drug will be in the patient’s body in the long run. 請問各位高手 這題應該要怎麼想 答案是5嗎? 還請指點一二 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 121.254.115.31
