The following problem is not difficult, however, I am having trouble calculating the answer using my HP 12c Platinum. Can you please provide a step by step explantation of how to calculate the answer to...


1. Make sure the HP-12C is in compounding mode. Press STO-EEX repeatedly until a tiny "C" appears in lower right of display.
2. Make sure "BEGIN" is NOT shown in the display. If it is, press g-END.
3. Clear financial registers: f-FIN. (That is really the "f" key then kind of the "Clear FIN" key -- I'm sure you'll see it.)
4. Enter zero as "initial investment". CLx, then g-CF0. (You have to do this because the 12C actually computes the "NPV" as an excess or deficit over the entered "initial investment". By entering zero, you force the calculator to just give you the actual net present value.)
5. Your first cash flow is +2.00. So, enter 2.00, then press g-CFj.
6. Next cash flow: +2.10. Enter 2.1, then press g-CFj.
7. Last cash flow: +22.20 (the final value of the stock plus the last dividend payment). Enter 22.20, then press g-CFj.
8. Enter the 10% interest (a.k.a. discount) rate. Enter 10, then press "i".
9. Compute the NPV. Press g-NPV. The answer is indeed 20.23 (at least to two decimal places).

Calculation of Poisson distribution


First, the Poisson Distribution describes events which have a small probability of occurrence at any very precise single value, like 3.546732190, but which nonetheless occur very very frequently in a range of values. Also the mean or average or expected value are the same as the variance, in your case, three (I think you meant three).

So looking up the tables for this (or plugging it in Excel) the prob x=4 exactly is 0.1680

Casio fx-83GT PLUS gives wrong values for logs


Are you using the right type of logarithms? The calculator provides for two types: common (base 10) and natural (base e).

Could you post an example or two, with the answers you get and the expected answers?

Getting overflow when trying 365! on Ti 83 Plus


What do you expect? The factorial function grows rapidly and the capabilities of your calculator are limited. If you check the calculation limit you will see that it cannot exceed 10^100 and this is achieved with 69!
Just in case you really need the value, here is an approximation of it.

When i put in a solution i get this err :syntax


This typically means that something you're inputted didn't follow what the calculator expected for a given input. This can happen if you put something in like "6++5" -- the calculator doesn't expect another function sign after "+", it expects something that has numerical value like a variable or an actual number! You can fix this by hitting [2] on the error screen, which will take you to the place where the calculator stumbled on the problem. From there, you can doublecheck what you typed in and try it again.

How to use the SIN botton EX: 25 x SIN(65)


Hello,

Before starting to enter the angle measure to calculate the value of a trigonometric function (sine, cosine, tangent) you must make sure that the current angle unit (degree, radian, grad) the calculator is configured to be using is the same that your problem requires. For instance, if you are solving a problem in which the angles are given in degrees you must verify that the calculator is configured to work in degrees.

When calculator is turned on, the angle unit is reset to degrees, but just to make sure it still is, look at the display: It should show the indicator DEG. If the display indicator is not DEG press the key [DRG] once or twice until you see the DEG on the screen.
The angle unit being taken care of, we turn to the actual calculation
Usually, to calculate the sine of an angle, you enter the angle value, press the [SIN] key and hit [=]. As you can see the sine function eats the number stored in its current register and calculates its sine.

To make sure that the calculator is taking the sine of 65 and not of 25*65, I would enter the calculation as follows
[65 [SIN] [*] 25 [=] : the result should be 22.65769468
or
25[*][ ( ] 65 [SIN] [ ) ] [=]

In the last key sequence, the use of parentheses forces the calculator to pause all previous calculations and wait for the closing right parenthesis. When the right parenthesis is entered, the calculator takes care of the contents of the parentheses first, then resumes the operations entered before the parentheses.

Importance of checking the angle unit before a calculation

Let us perform the calculation with angle unit
  1. in degrees : 25* sin(65) = 22.65769468
  2. in radians : 25 *sin(65) = 20.67071699
As you can see, the two values are not very far apart and since you are expecting a value that does not exceed 25 you might want to check your result.

Hope it helps.
Thank you for rating this solution

I totally forgot how to do binomial pdf can you help on my TI-84


Hello,
Press the yellow [2nd] key then [VARS] (DISTR) to access the distributions. Scroll Up or down to see 0:binompdf( . Press 0 |ENTER|. The command echoes on the screen as binompdf(. Complete the command by entering the number of trials, the probability of success, and the value expected. Number of trials, and the value expected are integers.
You can also run the command giving it a sequence of expected values. In that case the sequence of expected values must be enclosed in curly brackets
Hope it helps.
binompdf ( number of trials, p, { expec_value1, expec_value2, ...} ) [ENTER]

Explain brief about Goak Seek Command, Solver, Sceanerios


Goal Seek Solver and Sceanerios are a Part of What if Data Analysis Tools.
Goal Seek find the Expected Change in terms of value to a calculated Items.
For Example if you have a sales data for the year 2007 where Profit is 350000 and you want to make it 500000 for the year 2008 so what changes you will do in Product cost or Product Price this you will find with Goal Seek. It is also known as Back calculation. It has some restrictions which is overcome by Solver. But before doing this type of calculation use Sceanerios to store different Calculated values using Goal Seek and Solver. You dont have to add these values in different sheets all the values stored as a sceanerios. so You can show different Predections to the customers without moving around the Sheets.
