Help with Programming a HP 33S  Eric  03302006 I have a HP 33s and I'm taking the PE exam in April. I wanted to program the calculator to do some quick interpolations. I haven't programmed a HP 32SII or HP 33S so I'm unsure how to do this. Interpolation should be a simple program and would help with steam tables. In addition, it would save me time on the test. Can anybody help or point me in the right direction or get me started?
Thanks, Re: Help with Programming a HP 33S  Vieira, Luiz C. (Brazil)  03312006 Hi, Eric; if you want linear interpolation, you could use the statistical resources. You could enter the coordinates of the two points and use linear estimation to computer either Y or X value of the intermediate point. Unfortunately, the HP33S standard statistic functions do not handle logaritmic, exponential and power curves. If this is what you need and you still need further advice, let us know. Cheers.

Re: Help with Programming a HP 33S  bill platt  03312006 Like Luiz said, but I can add that the nonlinear interpolations are available, too. Ever since the 11c (and before) there have been routines for themand the 11c version will work fine (with minor syntax changes) as will the 32sii version. It is a relatively trivial program. Certainly making your own linear interp is trivialI've done it ad hoc many times. The museum has a cd/dvd available that has the 11c and the 15c manuals on it...
Let us know the outcome.
Re: Help with Programming a HP 33S  Eric  04012006 Thanks! I guess I'll have to look up this functionality in my manual. This could save me alot of time on the test. Thanks to both of you for responding... The HP 33S isn't as bad as everybody says I use a 32SII at work for daily tasks and my GX is a bit overkill and would make me look nerdy. :)

Re: Help with Programming a HP 33S  Ed Look  04012006 Yo! Hey! Nerd is cool! If I had a GX (I have the G and G+), I'd worry more about breaking it! I truly wish those 48s were rubber encased or something.
Re: Help with Programming a HP 33S  Vense Phonesouphan  04072006 Eric, I have a very simple program if you're just trying to do a linear inperpolation with known points. Me personally, I like the easier functions you can use to program in the HP 33s. I hope this is what you're looking for.
