1. Set the TI84 into the SEQ-mode.
nMin = the smallest value for n, best would be to start with n = 1
u(n) = that's OK. You know, that you have to type:
1.015825*(2nd) (7) ((APPS) -1)
The bold text in brackets mean the labels of the keys of the TI84
u (nMin) If I understand the "ui 1 = 4000" right then it is the start value.
Afterwards you have to adjust the window:
nMIN = 1
nMax = 50
PlotStart = 1
PlotStep = 1
Xmin = 16
Xmax = 16
Xscl = 1
Ymin = 3500
Ymax = 8000
Yscl = 500
Then I get a line. I don't know what you wanted to draw, but finally the TI84 draws at least something.
I hope this will help a little bit further.
