Signed area graph problem

[lrdheat]

Hi Mark,

I'm still wondering if such a graph is an artifact of the numerator becoming smaller than can be handled smoothly with a finite calculation resolution inherent in any mathematical software...

Without going into high level math, is there an intuitive explanation that would explain why the function should not approach it's limit of .25 smoothly?

I did let the Prime have several minutes to calculate signed area in the graphing app, and it did come up with a good answer.

Any idea as to why the WP 34S or CASIO 9860gii would be close to immediate in finding an answer vs what the Prime does in home and graphing?

Thanks for your thoughts!
