Free Ti-89 Titanium Calculator to a good home

#1

Post by PStamatiou »

I've been cleaning through some of my stuff/junk today, similar to that old PG essay about having too much stuff. Now I sit at my desk typing this with a mint condition Ti-89 Titanium calculator by my side. I've finished all the math courses for my degree so I haven't touched it in years.

I was going to sell it but I'd rather not go through the hassle of posting to CL and having to meetup with someone.

Tell me why this calculator would come in handy for you and I'll gladly send it to you, complete with manual. If you're overseas, I might ask for a bit of paypal $ to help with shipping.

I'd be happy to take it off your hands. I've got a few more math classes to go, and the higher-level CS stuff. I don't know how much that requires an 89, but symbolic integration/differentiation never hurt anyone. AFAIK it would be useful for crypto stuff, which I've been thinking about getting into.

I'm in Pre-Cal AP at my high school, money's tight and I would love to accept your calculator. The ones they provide at school for free don't have good graphing utilities :/.

Anyway, thanks for the consideration, it's nice enough to see someone offer such thing for free. :D

Edit: Money's tight at my house, but indraneel24 sounds like he needs it more. Please exclude me from this for his benefit. Thanks!

pstam! i'm starting my second year at UCLA, studying chem engineering. i have a couple more linear algebra courses and an upper div diffy eqn class to go. i currently have to go to the computer labs and pray there are computers with the right software available. with the TI I could get my work done in my appt and not have to pull allnighters in the computer lab.

I remember last summer going through your back to school lists before I left, and the only essential item I couldn't afford was the calculator. Take care man.

I'm in Pre-Calc H in high school, an my father has been out of work fo a few months, so money is tight. So while everybody has fancy 84s and 89s, I'm stuck with a school issue, really old and slow TI-83. Also, I want to get a computer science/ business degree when I go I college in 2.5 years; both math intensive degrees. Oh and my dream school is MIT haha. So yup I'd love an 89 - besides, I've been reading pstam.com for two years now ;)

As a funny sidenote -- I still hang onto my TI-89 as it's something that I can cary off with me to a location that's not my desk when I'm holed up with a pile of scientific papers and a spiral notebook. It doesn't have nearly the same distraction factor as a laptop. (The TI-85, on the other hand, could probably go. ;-) )

I'm a out of state Georgia Tech student double majoring in CS and Math and don't have any calculator at this point.

You should get a bonus for being conveniently close to Paul.

I believe we're both from Texas too. Oh I guess I should mention I'm paying my way through college myself too.
