20 Most Recent Texas Instruments BA-II Plus Calculator - Page 8 Questions & Answers

The calculator has different worksheets.
To access TVM worksheet, press [2nd] and any TVM key : N, I/Y, PV, PMT or FV
To enter Amortization worksheet, press [2nd][AMORT]
To access Cash Flow (problem with unequal cash flows) Press CF, or NPV, or CPT or IRR
To access BOND worksheets press [2nd][BND]
For depreciation worksheets press [2nd][DPR]
For statistics, use [2nd][DATA], or [2nd][STAT].
There are other worksheets [2nd][Delta%], [2nd][DATE], [2nd][PROFIT], [2nd][BRKEVN],[2nd][MEMory].

These shortcuts will not get you anywhere if you do not consult the manual.

To calculate the payment, press the CPT key then the PMT key.

I would suggest changing back to the old batteries

25 = 23e^x
25/23 = e^x
ln 25/23 = x

Press 2 5 / 2 3 = LN

Press 2nd [BGN] to toggle the setting, then press 2nd [SET].

Press 2nd [FORMAT] 4 ENTER.

There isn't one. You can calculate the common logarithm of any number by using the relationship
log x = ln x / ln 10. In words, calculate the log of a number by dividing its ln by the ln of 10.

The ln key is just to the left of the 7 key.

Correct.
53 ! = 4.27488328 × 1069

2 +/- 2nd [e^x]

+/- is the change-sign key, just to the right of the decimal point key.
e^x is the second function of the LN key, just to the left of the 7 key.

Hello,
On calculators you calculate permutations and combinations as follows
Enter the number n then press key nPr, and the number r
18(nPr)5=1028160

For combinations, use nCr key instead of nPr.
18(nCr)5=8568.

Hope it helps

Press 7 0 0 * ( . 0 4 * . 5 ) 2nd [e^x] =

Please refer to the link to formula involving loan calculation: http://www.docstoc.com/docs/64563308/Calculating-Loan-Payments-Using-Reducing-Balance-Formula

1 . 0 1 y^x 1 0 0 =

y^x is the key just above the 7 key.

GOOD QUESTION, Patweetyp...

I've got you covered.

Seeing how it's been three weeks since you posted this there's a chance you've already gotten your answer, but let me go ahead solve this for those out there who may have had the same problem.

Background: There are FIVE TVM Keys; and as you would assume, you MUST input FOUR of them in order for the BA II Plus to solve for the fifth. Now let's get down to business.

1. Hit CLR TVM. [This is just a cleanup maneuver]
1a. Hit ENTER [yes, BA II Plus always needs to be told to store the value, ALWAYS]
2. Type in -2400
3. Hit PV [Since you are investing money at time 0, your present value is negative 2400]
3a. Hit ENTER
4. Type 6
5. Hit I/Y [Your annually compounded interest rate is 6 percent]
5a. Hit ENTER
6. Type 0
7. Hit PMT [you do not have any recurring deposits*]
7a. Hit ENTER
8. Type 1
9. Hit N [there is one year until expiration/liquidation/termination]
9a. Hit ENTER
10. Hit CPT
11. Hit FV [this is your ANSWER = 2544]
----- From here, all you would need to do is change N in order to get your other answers (5 years, 10 years, etc) ----

*If your calculation does not require a recurring payment then you really just have a basic equation of value which would be solved faster by hand. (IE, 2400*(1.06)^1=FV=2544).

You'll notice that I underlined "annually compounded" as well as "one year". The reason for this is because you ALWAYS need your interest term to match your time interval. For instance, if you had monthly payments of which you wanted the year-end total you would need a monthly effective interest rate, and N would be 12.



Okay, I hope that helped. The BAII Plus is the best calculator for time-value-money calculations I've come across. When things get more advanced, you will start using the amortization table which cannot be found in any other TI Calculator (from what I know). TVM is perfect for annuities, mortgages, loans, bonds, and more.

Sorry, boss.

But getting standard deviation from a probability distribution would probably be best done by hand (of course, with the use of a computational device for those hard-to-reach fractions).

If your distribution question has a long line of events (IE, data points) then you'd probably want to use a more advanced calculator.

Nevertheless....I will return this afternoon with a more informed answer after I tinker with my BA-II Plus.

Whenever I do these, though, I usually pop open my TI89 Titanium (or of course just do it by hand).

STAY TUNED, MO...

Work with the simple formula: Interest = Initial * rate * time
To find the total amount, add the Initial plus the Interest, then subtract what has been paid. This will change the amount of money that will be accruing interest, though, so if there is a payment schedule you will need to repeat this calculation to get an exact number.
