Topic: bug?
Best graph program I have found! While I was looking through an old calc book and tried to answer the question lim as x approaches 0 of f(x) = (1/x)(Sin(pi/x)). The graph was great but as you zoom in (closer to 0) it starts to add more zeroes on the x axis. The question is, what is the minimum number you can enter before the program converts it to zero?
Also it came up with a value other than zero for Sin(pi/.01) when I calculated a table for it. Perhaps this too has to do with the smallness of the number? Harry
Re: bug?
It is a very difficult function to plot you have found. Though Graph in general try to avoid rounding I think 10^-14 is around the limit for what Graph can handle. But it might depend on the situation.
The reason you get a number like -1.2246E-14 instead of zero for sin(pi/.01) is that the processor calculates with a limited number of decimals and it is apparently the result the processor gives for sin(100pi).
Re: bug?
Thanks for you quick answers. Your program is still the best and I couldn't beat the price. Harry
