Window Variables The Window Editor maintains an independent set of Window variables for each Graph mode setting (just as the Y= Editor maintains independent function lists). Sequence graphs use the following Window variables. Variable nmin, nmax plotStrt plotStep xmin, xmax, ymin, ymax xscl, yscl Description Smallest and largest n values to evaluate. Sequences are evaluated at: u(nmin) u(nmin+1) u(nmin+2) ... not to exceed ... u(nmax) The term number that will be the first one plotted (depending on plotstep). For example, to begin plotting with the 2nd term in the sequence, set plotstrt = 2. The first term will be evaluated at nmin but not plotted. Incremental n value for graphing only. This does not affect how the sequence is evaluated, only which points are plotted. For example, suppose plotstep = 2. The sequence is evaluated at each consecutive integer but is plotted at only every other integer. Boundaries of the viewing window. Distance between tick marks on the x and y axes. Note: Both nmin and nmax must be positive integers, although nmin can be zero; nmin, nmax, plotstrt and plotstep must be integers , 1. If you do not enter integers, they will be rounded to integers.
