(dc/(P+km−mc))=(dt/M)  ∫(dc/(P+km−mc))=∫(dt/M)  −(1/m)ln (P+km−mc)=(t/M)+U_1   −Mln (P+km−mc)=mt+U_2   ln (P+km−mc)=−(m/M)t+U_3   at t=0: c=a   ln (P+km−ma)=U_3   ln (P+km−mc)−ln (P+km−ma)=−(m/M)t  ln ((P+km−mc)/(P+km−ma))=−(m/M)t  ((P+km−mc)/(P+km−ma))=e^(−(m/M)t)   P+km−mc=(P+km−ma)e^(−(m/M)t)   ⇒c=(P/m)+k−((P/m)+k−a)e^(−(m/M)t)
