Question about Casio FX-115ES Scientific Calculator

You may be writing the expression as they appear in the formula, but the problem stems from the fact the factorial function increase rather rapidly and you cannot calculate the factorials of numbers larger that 69 which is the limit of the calculator.

However if you use the built in Combination function nCr, you will avoid the problem. In the binomial function, the n!/(r!(n-r)!) factor can be replaced by nCr or nC(n-r).

Do not use the explicit form with the factorials because you will get an overflow.

This is a scientific calculator that can perform many operations on numbers but not on letter symbols. It does not have a Computer Algebra System.

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).

When entering the information it only shows the degree symbol. If you press enter or type inthe formula, then the answer will show the Degree, Minutes, and seconds. It seems to be the way it was program by Casio. It still seems to work fine for entering that information

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.

The binomial probability distribution is defined as

P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r), where n is the number of trials, p the probability of success, and r the expected result.

Let n=20, r=7, p=0.15 ( I do not know wether this exemple has any meaning in the context of your problem, but you have to enter values that mean something to you.) I am only showing you the key strokes

To enter 20C7 you press 20 [SHIFT][nCr]7 ;

To enter 0.15 to the power 7 you type 0.15[X to ] 7 the key is between

[x²] and [log]

To enter (1-0.15) to power 20-7, you type 0.85 [X to] 13

With [*] standing for multiplication key , and [X to] the raise to power key, the exemple above can be entered as

**( 20 [SHIFT][nCr] 7) [*] ( 0.15 [X to] 7 ) [*] ( 0.85 [X to] 13 ) [=]**

Here is a screen capture to show you what it looks like. However on this calculator the combination 20 [SHIFT][nCr] 7 is represented as nCr(20,7).

P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r), where n is the number of trials, p the probability of success, and r the expected result.

Unless I am failing to understand your problem, just combine like terms to get:

9x^2+2x+4 and then enter those coefficients into the quadratic solver.

That will get you the two answers -- both of them will be complex.

If you wanted to turn those two answers into factors (complex) of the original equation simply

change the signs on each and put an x in front.

Of course, the quadratic formula would also work.
