Important If the difference between the minimum and maximum values you set for the pitch of T or 0 is too great, your graph will be too rough. If,the difference is too small, drawing of the graph will take a very long time. INSpecifying the Graph Range When graphing a parametric function, you can specify the maximum and minimum values to be applied. Use the following format. functionEl=ilT) Tmin E Tmax CIE Example To graph the following functions: x=7cosT-2cos 3.5T y=7sinT-2sin 3.5T Use the following range: ≤ T ≤ 2r EIRCLS)g D(Rad)0 ITCIRIECUM CIEU ELlannIC1ErEaMEITI EIECIMMEITIM ECM -164- 8-5 Inequality Graphs To draw inequality graphs, first change to the IN0 Mode. Do not try to use the BASE, EQUA, DYNA or TABLE Mode for graphing. The functions that can be graphed in the INQ Mode are those that fit one of the following formats: Y > f(x) Y = f(x) Y < f(x) Y f(x) • Important Whenever drawing a new inequality graph, you should always start out with EUERas)g to clear the display.
