Hi, Matt --
Long time no post!
Thanks for the link; I'd forgotten about the HP Solve newsletters. They don't measure up to the old Hewlett-Packard Journal, but the time, effort, and budget funds expended are not even remotely comparable.
This headline from the December 2008 issue was a bit startling:
Technical corner: Sinus, Cosine and Tangent
To find the Sin, Cos and Tan of a number, some heavy trigonometric
algorithms are needed. Make it easy with your HP calculator and these step-by-step instructions.
"Sinus"? Sure, "Sin" and "Cos" are sinusoidal, but...
And why are "heavy trigonometric algorithms" and "step-by-step instructions" necessary? Wouldn't a single keystroke provide the desired answers?
As it turns out, the three-page article describes the CORDIC algorithm. Maybe this time it'll make sense to me, as published references and Eric Smith's thoughtful summary of almost two years ago haven't quite done the trick...
"Coronate rotation" and "Cartesian plan" slipped through proofreading in the article. ;-)
A recap of HHC 2008 with group photo is in the same issue.
