HP 42S is largely known to be a two line Scientific RPN Calculator. I just wanted to demonstrate its' graphing capability with this video. The display can also be used for graphics. I run "DPLOT" from the owners' manual and call the program to calculate the SIN function. As you see the limits are from -2pi to 2pi on x-axis and -1 to 1 on y-axis. Origin is 0.
