•Specifying the Graph Range When graphing a functionwith the format "y= function!, you can specify-the maximum and minimum values to be applied.

When you graph a built-in function, the range parameters are set by the unit automatically. The functions that can be graphed in the. POL Mode are those that fit the following format: r =f(0• ) Note that you should specify polar coordinate graphs. • rads L. as the unit of angular • measurement when -• graphing IN Graphing Built-In Scientific Functions Use the RUN/COMP Mode to draw polar coordinate graphs. Do not use the BASE, EWA, DYNA or TABLE Mode. When you graph a built-in function, the range parameters are set by the unit automatically. -160- •Graphing Manually Entered Functions You can graph manually entered functions by simply p essing ElE3 and then entering the' function. Manually entered functions must have the following format: Graph r= re function] Remember that you also have to specify range parameters (page 153): • To graph a manually entered function Example To.nraph 0_-.2sin30 using the following range parameters: . .
