My HP35 bit the dust many moons ago (and sadly, I disposed of it). I powered up my 1977 TI30 this afternoon, and got the following result from COS(89.9999):

It took almost two(2) full seconds to calculate this cosine (and its off by 1 in the last place); and even though its correctly rounded in the last place this answer (which is zero by all engineering standard) is not nearly as accurate as the answer I get from the HP35s!

My 1973 HP-35 gives: 1.7451419E-06

Interestingly, I get 0.0000017 on the TI-55 compared to 0.00000175 the TI-30. I can't figure out how to insert the image (looks like I have to upload it to a url...???). What is the easiest way to upload images for insertion?
