Best way to write some equations and generate a graph

[EDIT: 20110601 11:35 CDT - reformat - WDR]

I have equations that feed into each other that are written into functions. What is the best way to execute all of them in one fell swoop and generate some graphs?

Ex:

where t1,t2,t3,t4 are all arrays of values:

x = {(t2[n] - t1[n]) + (t4[n] - t3[n])}/2
y = (t2[n]-t1[n]) - x
z = {(t2[n+1] - t2[n] + y/alpha)/(t1[n+1] - t1[n])} - 1

say I now want to graph values of x vs. z, what is the best way to do this?

Thanks!

Is n a scalar, or is it supposed to be in a loop? If it is loop index, what is the range?

x = {(t2(n)-t1(n)) + (t4(n)-t3(n))}/2
z = {(t2(n+1)-t2(n) + ((t2(n)-t1(n))-x)/alpha)/(t1(n+1)-t1(n))} - 1
