Graph of X*Sin(X) incorrect HP50g
Graphing the function X times Sin(X) displays a Horizontal Asymptote at positive 1.
I am in radian mode using RPN. Can anyone tell me how to display the correct graph? Cheers! |

RE: Graph of X*Sin(X) incorrect HP50g
Works correctly on my 50g. Did you clear the previous graph before you plotted x*sin(x)?

RE: Graph of X*Sin(X) incorrect HP50g
Thank you Brad for responding.
My Bad. I meant to use X times SIN(1/X). Cheers! |

RE: Graph of X*Sin(1/X) is fine

This function indeed approachs +1 as x approaches infinity: This means that 1/x approaches zero and thus sin(1/x) ≈ 1/x so that the limit is x · 1/x = 1. So there is no problem with the 50G. Dieter |
