On Casio FX-115ES Plus Calculator, what buttons do I push to do compound interestsemiannually for 15 years?


There is no such button. You must figure out the formula and enter it, giving the appropriate value for the annual interest and the number of years (15).

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.

Quadratic equation fx-82ms


You can do it the same way people did it before calculators were invented. Just use the quadratic formula: http://en.wikipedia.org/wiki/Quadratic_formula, and let the calculator handle the arithmetic. Some sophisticated calculators have generalized equation solvers that can handle equations much more complicated than the quadratic, but the fx-82 isn't one of them.

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).

What calculator would you recommend for polar and rectangular formula's?


Are you serious?
No calculator purchase should be solely based on such a trivial matter.
But if you are looking for a very good scientific calculator, I would suggest the new Write View EL-W506/W516/W546 calculators by Sharp, or the FX-115ES/991ES Natural Display by Casio.

With these calculators you can see what you enter displayed as in textbooks. Naturally, they all do coordinates conversions from Polar to Rectangular and from Rectangular to Polar.

Does anyone know how to calculate derivatives using the casio fx-115es? For example: find the derivative of f(x)= 3x^3=3x. Thank you!


hello,
The calculator will calculate the derivative at a point. It will not give you the formula for the derivative, just the derivative at the point you choose.
Sorry, it can ONLY do NUMERICAL differentiations and integrations.
