For or If loop with system of equations with initial value of zero.

Hello can someone can help or guide me to creating this code. I have a system of equations that I want to insert into a for or if loop. The first equation has variables from the second equation but can be considered to be zero initially, this goes for the following equations as well e.g. y1=exp(y2*t)/exp(t), y2=exp(y3*t)/exp(y1*t) etc where t is time. After the first iteration I want to insert the already calculated value into their respective variable. Any help will be appreciative Thanks.

You have two equations and four variables, y1, y2, y3, t. Are there any other equations? What are you trying to do with these? Plot or solve for the y's over a range of t's? Or what?

There are 6 sets of equations and well I want to be able to plot it after a certain number of iterations.

What are the equations?

something like this

y1=exp(y2*t)/exp(t)

y2=exp(y3*t)/exp(-y1*t)

y3=exp(y4*t)/exp(-y2*t)

y4=exp(y5*t)/exp(-y3*t)

y5=exp(y6*t)/exp(-y4*t)

y6=exp(y5*t)/exp(t)
