The TI-83 has four graphing modes.
• Func (function graphing)
• Par (parametric graphing; Chapter 4)
• Pol (polar graphing; Chapter 5)
• Seq (sequence graphing; Chapter 6)
Other mode settings affect graphing results. Chapter 1
describes each mode setting.
• Float or 0123456789 (fixed) decimal mode affects
displayed graph coordinates.
• Radian or Degree angle mode affects interpretation of
some functions.
• Connected or Dot plotting mode affects plotting of
selected functions.
• Sequential or Simul graphing-order mode affects
function plotting when more than one function is
selected.
To set the graphing mode and other modes from a
