For example, CAS.diff and CAS.zeros. <br /><br />If you are working with algebraic or symbolic objects (such as functions or polynomials), you may have to enclose them with single quotes (Shift + Parenthesis key). <br /><br />Example in Home Mode:<br />CAS.diff('X^3-2') returns 3*X^2<br />CAS.zeros('X^3+4') returns [-1.58740105197] <br /><br />I recommend using zeros instead of solve in Home and programming mode. <br /><br /><br />EddieEdward Shorehttps://www.blogger.com/profile/13278913865743064653noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-80523233123184351472013-12-16T08:22:22.098-08:002013-12-16T08:22:22.098-08:00I like your tutorials very much.

It works well in the CAS view, but it doesn't in a program, not even with qualified variables or commands.

...Alright, another fine entry from Ed, good stuff.<br /><br />Prime vs. 50g, they both have pro and cons, I like the fact that the 50g uses disposable batteries, so I'm never dry. Color? Well, I can live without. Zeta function, hah, if you knew how many times I've used it in my entire life...<br /><br />It's good to see that HP is building advanced calculators again, I wasn't really sure the 50g wouldn't be the last one. As far as the prime, well, I've done all my studies with a 48gx and that was my generation's calculator. The Prime is probably targeted at people much younger than I.<br /><br />I use the 50g almost on a daily basis, and when I need to do some heavy lifting, I still rely on Mathematica, I'm not sure the Prime could replace either one, at least for me. I've never used anything but reverse polish on a calculator, I'm not sure I have the time or devotion to learn a new language; but if my son gets one, I'm sure I'll pick up one as well and start investigating.<br /><br />That being said, I'm going to follow your series on the Prime very closely, but I'll stick to my 50g for the time being. It works for me.<br /><br />Cheers!veganmanhttps://www.blogger.com/profile/12110683523619624358noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-64579883361463321582013-10-26T14:25:07.126-07:002013-10-26T14:25:07.126-07:00Very nice.
