From Wikipedia.
Mathematically the experience curve is described by a power law function sometimes referred to as Henderson's Law:

  • is the cost of the first unit of production
  • is the cost of the nth unit of production
  • 95ae10911ccd94b57da5535ac94fec03.png is the cumulative volume of production
  • is the elasticity of cost with regard to output[

If that is the law involved you enter it as follows

60000*500[ ^ ] [(-)] 0.415 [=] result should be 4550.705

[ ^ ] is the power key, between x-square and log
[(-)] is the change sign (or negation) key in the leftmost column, just above [RCL]

Hope it helps.

    Sorry, what I stole from Wikipedia was stolen from me by FixYa.
    The formula is C_n =C_1* n^(-a)

    C_1 is the cost of the first unit of production (60 000)
    C_n is the cost of the nth unit of production
    n is the cumulative volume of production (500)
    a is the elasticity of cost with respect to output (0.415)

    Here is a picture to show your calculations. The formula is on line 4. The result is on line 5. You can have more decimals in your result.

    You enter your calculation as on the 6th line.

    The minus sign is (-) change sign key, just above RCL. To raise to a power use the key between Xsquare and log.

Bought a Casio FX-260 calculator. Im trying to find out how to input a trig formula. E.g 2/cos(70)= 5.84 When I do put this in the calculator in scientific mode it gives me a different answer. Help?

I'm guessing that your calculator is set to radians or gradians (or degrees, if you are looking for a result in radians or gradians).

Try changing this and hopefully it will work.

Otherwise, post again!

Good luck,

My casio FX 991ES is giving formula answers, to a calculation using a large exponent number in a formula answer, I need it to tell me a long number instead. Sum is 6.7 x 1018. The answer I get is 6.7x1018,...

Your answer is 6.7*10^18. That requires 19 places on the display: There are not enough places to write that. Besides, calculators are deigned to use Scientific Notation whenever the result to be displayed is too large or too small.
If you enjoy writing zeros, convert by hand the scientific notation into what you call long number.

How do i input a log base

Not with the calculator I see in the picture. If the scientific calculator does not have a specific key to enter log_in_base you can use the equivalent formulas.

Save equation fx 991es

In table Mode you can enter the formula for a function and generate a table of values. For a 991ES Plus you can enter two functions. However if you change MODE everything will be erased.
In EQN (equation) there is a certain number of built in formula types you can choose. You will be asked for the coefficients which will be used to solve the equation selected. However if you change MODE your lose what you entered. So basically you cannot save formulas to use as a memory aid (if that is what your intention is.) Sorry.

How I can memorize my own formula (expression) in memory of FX 991 ES for using in future, step by step ?

Sorry, but you cannot.
You can type in a formula that involves the memory variables X,Y, A, B,C,D, E, =, . Such a formula is meant to be evaluated to get a solution (X by default). Once you type the formula you press the Shifted function SOLVE and you will be prompted for the constants, for Y etc. when you press the EXE/= key you get the value of X.
If you turn off the calculator or change the calculation MODE, it is wiped out of memory.

To make a long story short, you cannot STORE formulas in the calculator. Better try to memorize them (commit then to YOUR OWN memory).
