Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

Ad

Seems crazy, but this is the second time today this question has come up.....

The TI84 won't allow two investments. It will let you do as many Cash Flows as you want, but only one investment.

The only way to work this out is to use another tool. A spreadsheet would be best, but if you don't have access to one, we can work up the equations and do it by hand, or maybe simplify it to a point that the TI can work it out in pieces.

You tried to use an argument to a function that was not in the function's domain. For example, the arcsine function takes an argument from negative one to positive one. Trying to take the arcsine of 2 will generate a domain error.

If you need further assistance, please specify the exact function and argument that is generating this error.

Could you provide some details? The inputs, your exact keystrokes, the result, and the expected result, for starters.

binomcdf() takes two or three arguments, but you're providing four. The first argument is the number of trials (7 looks good for this), the second argument is the probability (.25 looks good for this), and the optional third argument is the number of successes (2 in your case).

Try binomcdf(7,.25,2)

Try binomcdf(7,.25,2)

If you were trying to find the roots (zeros) of an algebraic equation
with the solve( command or the interactive solver you might have
supplied an interval where the function is always positive or always
negative. If the expression is always of the same sign on an interval,
the interval does not contain a root.

- If you extend the interval, the procedure may not converge fast enough and the calculator may not find the solution.
- Abetter way to do it is to sketch the graph of the function and use the graph to choose a reasonable interval that extends on both sides of the root, and a better initial guess.

- You attempted to calculate the I% variable when FV, N*PMT, and PV are all positive, or all negative.
- You tried to calculate Irr( when neither CFlist, nor CFO is positive
- You tried to calculate Irr( when neither CFlist,
nor CFO is negative

The IRR function is provided by Excel so you can calculate an
internal rate of return for a series of values. The IRR is the interest
rate accrued on an investment
consisting of payments and income that occur at the same regular
periods. In the values provided to the function, you enter payments you
make as negative values and income you receive as positive values.

For instance, let's say you are investing in your daughter's business, and she will make payments back to you annually over the course of four years. You are planning to invest $50,000, and you expect to receive $10,000 in the first year, $17,500 in the second year, $25,000 in the third, and $30,000 in the fourth.

Since the $50,000 is money you are paying out, it is entered in Excel as a negative value. The other values are entered as positive values. For instance, you could enter –50000 in cell D4, 10000 in cell D5, 17500 in cell D6, 25000 in cell D7, and 30000 in cell D8. To calculate the internal rate of return, you would use the following formula:

=IRR(D4:D8)

The function returns an IRR of 19.49%.

The ranges you use with the IRR function must include at least one payment and one receipt. If you get a #NUM error, and you have included payments and receipts in the range, then Excel needs more information to calculate the IRR. Specifically, you need to provide a "starting guess" for Excel to work with. For example:

=IRR(D4:D8, -5%)

This usage means that the IRR function starts calculating at –5%, and then recursively attempts to resolve the IRR based on the values in the range.

Make sure the first argument is a number between 0 and 1, inclusive. Make sure the second argument is an integer or a list of integers.

Ti 83 and ti84 really have no difference and operate the same. There was something different or you had varibles used by multiple programs that conflicted w/ the ti84 and it would have done the same on the ti83. If you like to rework it and need help email me at raklein62@yahoo.com

Are you using the finance app?

[APPS] [1] [ENTER]

For NPV, choose "7:npv("

Then use:

npv(interest rate, cost {cash flows}, {frequencies of cash flows})

For IRR, choose "8:irr("

Then use:

irr(interest rate, cost {cash flows}, {frequencies of cash flows})

[APPS] [1] [ENTER]

For NPV, choose "7:npv("

Then use:

npv(interest rate, cost {cash flows}, {frequencies of cash flows})

For IRR, choose "8:irr("

Then use:

irr(interest rate, cost {cash flows}, {frequencies of cash flows})

if your analysis is based annually, yes. if it is based quarterly, then you have to raise the derived irr to the 4th power (4 consecutive quarters) to arrive at the annualized irr.

Jul 04, 2008 | Microsoft Excel for PC

Use the "FINANCE" app:

[APPS] [1] [ENTER]

for npv: select "7:NPV"

now you should get "npv(" on your screen.

use: npv(interest rate, cost {cash flows}, {frequencies of cash flows})

for irr: select "8: irr"

"irr(" will come up.

use: irr(interest rate, cost {cash flows}, {frequencies of cash flows})

[APPS] [1] [ENTER]

for npv: select "7:NPV"

now you should get "npv(" on your screen.

use: npv(interest rate, cost {cash flows}, {frequencies of cash flows})

for irr: select "8: irr"

"irr(" will come up.

use: irr(interest rate, cost {cash flows}, {frequencies of cash flows})
