Input Comment
1 C0 = 1 initial concentration of the sample
2 tm=3 dead time
3 β=2 phase ratio
4 n=100 number of plates
5 v(t,K)=tntm(1+K/β) Equation (9) *
6 f(t,K)=11+KC012πn(v(t,K)n)nen-v(t,K) Equation (4) *
7 f(t,1) simulating profile of K=1
8 f(t,3) simulating profile of K=3
9 f(t,5) simulating profile of K=5
10 f(t,7) simulating profile of K=7
11 f(t,9) simulating profile of K=9

* When typing equations (9) and (4) in GeoGebra, add parentheses after function symbols and specify the independent variable.
