BA II Plus Calculator (new for the fall)

[glenn]

I just bought one of these, and it looks pretty good.

It's got a whole whack of financial functions, plus trig functions. From the package:
-cash flow analysis for up to 24 uneven cash flows, computes NPR and IRR
- bond price or yield to maturity two-day count methods
-daily accruals with days-between-dates calcs.
- list based one adn two variable statistics with four regression options: linear log, exponential and power.
- Break even calcs, interest conversions, delta %, profit and loss.

The best part is that all of the following functions are on their own keys (don't need to us 2nd or fn to use them):
()
x²
y^x
ln
1/x
x^1/2

It's also got factorial, and a bunch of other functions I haven't looked at yet. All in all looks like a good choice for the fall.

glenn:

do you think it will be useful for exams II and above? For exam IV, do you suggest using the new BA II PLUS or the TI 30 IIS ?

by the way, just curious: what exam are you on?

[glenn]

I've got a 30XIIS and a BA35. The new BA II Plus has the best features of both.

I didn't write 2, I'm guessing some of the financial functions may be of use on that exam. I'm planning on writing 4A (Course 4 Again), and this will be the calculator I plan on using. Having ln and the parentheses on their own keys is worth the price of the calculator alone IMO. My big 'ol fingers frequently mess up on the calculator keys, so fewer keystrokes is good.

I have had one for about a year. While it's more powerful, I don't find it's functions intuitive. I'm sure it will be no problem to use it once I start practicing with it regularily.

I believe it does fix the irritating lack of order of operations support from the BA35 model.
