Full Version: Kahan's "weird" integral revisited
You're currently viewing a stripped down version of our content. View the full version with proper formatting.

Just to let you know that the otherwise much maligned TI83 Plus gives for Kahan's famous integral 10 good digits in under a minute for the original form of the integrand, and does the same thing much faster (a few seconds) if the x = w^2 substitution is used.

I might not like the look and feel for the calc, but I have to give it its due here. Even the 49G+ and 33S, which are supposed to have the advantage of modernity and speed, take a few minutes to give, say, 8 digits.

Just thought I would share that, if only to distance ourselves a little more from all of the heated stuff regarding buying and selling, etc.

HP's SOLVE is still based on the old HP-34C SOLVE that Kahan was behind. TI uses newer (and better) algorithms.
