Formula:

Log10(P)=A-(B/T)-C Log10(T)+DT+E(F-T)/FT*Log10(F-T)

Here A,B,C,D,E,F are all Constant Values. And I am having the value of P. Now I Need To Find Out The Value Of T. How To Solve This Problem and Can i get One Summerized Formula for to calulate the T.

Hello,

If you are comfortable manipulating such an expression, I suspect your are also very able to scour the research litterature to find out if the unsung hero who has found a way to express the pressure in some non ideal fluid with 6 virial coefficients, has also provided a short and sweet way to solve for the temperature. (My guess).

To lift any ambiguity in the expression use extra parentheses in your last term:where does the denominator stop?

My suggestion is that you write a program to solve numerically for T
or use some powerful software like Mathematica to obtain an
analytical solution.

Good luck.

If you have the formula you can use the calculator to find future values. But do not count on this calculator to do it for you. It does not have a business/finance application.

Each solid with a regular shape has a formula by which its volume is calculated. Once you know the formula to use and the values of the dimensions, just enter it in the calculator as it appears on paper (almost) and press** enter/EXE/=**

Make sure that the values of sides, radii, heights that are involved in formula must be expressed in the same unit.

The resulting value of the volume has unit

Unit_volume= (Unit of length used)^3

Well it depends. If the hexagon is irregular (sides are not equal) there is no formula to calculate the sides as they can have arbitrary values. You must measure them.

If the hexagon is regular you may be able to relate the measure of a side to the radius of the circle in which it is inscribed. If you have the radius of the circle, the side is equal to the radius. If you have the value of perimeter you divide that value by 6.

There is also a formula that relates the area of the hexagon to the measure of the side s. The formula is Area=(6/4)(s^2)cot(PI/6), where cot is the cotangent function, its angle is in radian. In degrees Pi/6 is 30 degrees.

I am not sure there is a question expressed here. If you have a formula you want to use to calculate some quantity in it, state the formula, provide the known values and we will show you how to enter it. As to what it serves for, I for one do not need to know.

Enter the formula as an equality. Then, with the cursor on the formula, press 2ND [F6] to select Style. Choose "Above" or "Below" depending on which side of the graph you want shaded. Then press diamond [GRAPH] as usual to see the graph.

Use the equivalent formula log base b of a is equal to [log10(a)]/[log10(b)], you can also use ln(a)/ln(b), the results will always be equivalent

There is no special setup. You just have to have the formula in front of your eyes and type in the numbers as you would by hand.

The area of a trapezoid is given by

Area= (measure of Longer base PLUS measure of shorter base) * (measure of height) /2

If A is the measure of the longer base, B the measure of the shorter base, C the measure of the Height --ALL EXPRESSED IN SAME UNIT--you can type in the formula (in MathIO display mode) as

0.5 [*] [ ( ] A [+] B [ ) ][ / ] C [=]

You can also store the values in memory. To store a value, enter the value then press [SHIFT][RCL] and the key that has the letter next to it. For A it is the change sign key [(-)]

Ex:

15 [SHIFT][RCL] A

10 [SHIFT][RCL] B,

7 [SHIFT][RCL] C

To calculate, you have to recall the values stored in the variables by pressing [RCL] A, [RCL] B, [RCL] C and use the key sequence

0.5 [*] [ ( ] [RCL] A [PLUS ] [RCL] B [ ) ][ / ] [RCL] C [=]

Do not forget the parentheses to enforce the priority rule for operations.

If you are in MathIO, you will be able to verify the correctness of the formula before you press the [=] key to evaluate it.

Your field, terrain, figure has a particular form. For each form you have a formula that tells you how to compute the area enclosed. Read your book or your notes to know what formula to use. I cannot give you a formula because I have no idea about the shape of the figure nor its dimensions.

Now, having the formula at hand you can use your calculator to calculate the area. But, in order to obtain consistent values you must convert all dimensions to the same unit length: m, cm, km, inches, feet or what have you.

For example: You have a rectangle with LENGTH L=3.5 m, and a width W=20 dm (decimeters), you must convert the value in decimeters to meters, 20 dm=2 m.

The area of you rectangle will be

Area=L*W=(3.5 m)*(2 m)=3.5*2 m*m= 7 m^2

Hi,

Yes you can calculate numerical values of in tegrals. The function is called**fnInt(**. It is accessible through

**fnInt( expr,var, lower_limit, upper_limit)**, to use default tolerance or

**fnInt( expr,var, lower_limit, upper_limit, tol),** tu use your tolerance.

In the commands above,

Thank you for using FixYa.

Don't forget to rate the solution.

Hello,

There is no point in entering a formula the calculator cannot use:It cannot do symbolic algebra. But if you want to calculate the focal distance f, knowing the values of the positions of the object and the image, you can transform it a bit and isolate f.

f=o*i/(o+i)

** o [x] i /(o[+]i) [=] **Here o, i are values for o and i, [x] multiply by, [+] plus.

If you cannot establish this formula (to your satisfaction) you can proced follows to obtain f.

**( o^(-1) +i^(-1))^(-1)** gives f.

The key [^(-1)] is labeled [X to the -1] or [1/x].

Hope it helps.
